Primal Endurance: An approach to making low carb endurance running work

Image result for primal blueprintBack in 2011, famous Primal Blueprint guru Mark Sisson wrote a post about how he’d train for a marathon. Mark’s no novice when it comes to distance running: He is in fact a former marathoner! His conversion to the lower-carb, paleo-style Primal approach to eating and lifestyle is in no small part a byproduct of his experience training to race the longest run.

Sisson of course generally discourages any sort of endurance training, prefering a more biologically natural sprint-and-saunter approach to outdoor activity akin to our prehistorical ancestors. Like many paleo-minded humans he’s more into occasional high intensity low duration activity surrounded by lots of regular but very low intensity activity.

This level of activity is of course a better fit for a lower carb Primal style diet, as endurance training traditionally requires a very high carb intake… intake that Sisson’s experience and research taught him can be damaging to your long term health.

However, a lack of carbohydrates can compromise the quality of your endurance workouts, let alone your race performances, since your body typically utilizes glycogen for extended endurance activity.

Sisson historically has preferred to avoid endurance training entirely and focus instead on what he’s found to be a more long-term sustainable lifestyle. His 2011 piece was more of a hypothetical, ‘If I had to train as a Primal disciple to run a marathon this is how I would approach it.’ Sisson’s piece definitely hinted that he had far more intel behind it, and that there was probably a book in him on the subject.

Image result for primal enduranceWell, eventually he did write that book. Primal Endurance by he and Brad Kearns spelled out the ideal combination of the Primal diet and lifestyle with the ideal training approach to maximize your performance in a marathon without the usage of carbohydrates and their glycogen.

I’ve given the book a gradual read over time, and while a lot of it reads like sales-letter filler for the Primal Blueprint (which seems superfluous since you probably aren’t reading the book unless you already own, have read and believe in the Primal Blueprint), what remains after filtering through it is a compelling and well-written approach to training as a Primal endurance athlete.

Sisson of course is hardly the only believer that endurance athletes can succeed with a lower-carb approach. Many ultra-runners have sworn by training low-carb to train their bodies to maximize fat usage in their excessively long races. Other non-ultra runners have sworn by training low-carb as well (I even know a few!).

I’ve long since argued (as many do) that accepting this lifestyle and swearing off most carbohydrates does to some degree limit your capability as a distance runner. In principle, I still find that to be true.

But there’s no denying that long term the endurance diet and lifestyle does take a toll on your hormones and to an accordant degree your health. I recall half marathon champ Ryan Hall being forced to retire in his early 30’s due to wanting to start a family and his training lifestyle compromising his body’s ability to do so.

I do think there’s a middle ground, mostly that you train in cycles and that you take breaks from training and the diet it demands. However, Sisson and Kearns argue that their recommended lifestyle can be practiced year round, in and out of training, without damaging your race performance.

Running coaches should coach diet and rest too

Every running coach will give you a training schedule of workouts, when to do them, how to do them, and how to adjust those from day to day.

Very few running coaches will give you more than trivial, general feedback on how to eat between workouts, or on your resting and sleeping habits. This despite your diet and recovery being even more important than what you’re doing in workouts.

Without the nutrients of a sound diet, you will not recover properly between workouts. And without a proper amount of sleep, you will not recover properly between workouts.


So, there’s obvious complications to coaching a person’s diet and sleep along with their running.

What makes diet and sleep hard to coach is that, unlike what a runner does in their workouts, these are everyday-living factors beyond a coach’s control. A coach may or may not be able to stand watch over your workouts (many athletes are coached remotely), but there’s no way they can stand and watch your every move, let alone every meal, in your personal life. And they certainly can’t monitor when or how you go to sleep. Even if they told you what to do, chances are good you’d flake on a good portion of their instructions. And, of course, who wants to have their lives micromanaged? The advice probably wouldn’t be welcome for many.

Plus, there are countless different approaches to diet even within a given culture, let alone between cultures. Those who have tried to bean-count the caloric intake of athletes have produced more problems for those athletes than they solved in doing so. Never mind the substantial differences in a vegan or carnivore or Atkins diet. Even the macronutrient needs can vary from person to person, never minding their age/size/shape/health in general.

Most of all, coaching diet is considered the field of a dietitician, a field outside of the specialty of a coach better versed in crafting and moderating workouts.

Now, all of that said (and no, I’m not providing any scientific citations), I can posit that a large number of injury and burnout problems are in no small part a product of deficiencies in each said athlete’s diet and sleep. The vast majority of humanity, in all fitness levels, is deficient in one or more key nutrients, whether it’s as simple as protein or as micro-specific as a vitamin like magnesium or iron.


Still, you don’t need to be an RD to know that:

  • The first half hour following a workout is the best time to ingest protein and carbs
  • Clean unprocessed food is better fuel between workouts than processed food
  • On average you ideally consume as many calories as you burn in a given day
  • You need more protein than most would recommend if you’re going to train hard
  • The more intense aerobic effort you put in, the more carbohydrates you need to consume between workouts
  • The harder you work on a given day, the more sleep you need that night to recover most effectively

The only resource that I’ve seen address post-workout nutrition with any specificity is Matt Fitzgerald’s New Rules Of Marathon And Half Marathon Nutrition. The book’s recommended workouts are bookended by a recommendation of carbohydrate/protein volume to consume in the minutes following a workout. The book is written around learning to effectively fuel a workout, and the information in general is a bit dated (the book was published in 2013), so its use is a bit limited. But it’s still more feedback on training nutrition than most authors provide.

The subject of what to eat between workouts is a broad and sensitive one, granted. It’s one I’m not going to get into now.

But I do think it’s a subject that running coaches need to give more than mere typical consideration. It’d be helpful to at least get a baseline idea of how many calories a runner consumes, estimate how many they burn per mile and during other exercise, get a good grasp on what the runner prefers to eat, and come up with some sort of concrete plan of what they should eat between workouts.

(And if you do actually want to become certified, there is a path to that. It’s not free, and it does take time, study and effort, but you can do it.)

A Gluten Free Diet Is Actually Really Simple

abundance agriculture bananas batch

Photo by Pixabay on Pexels.com

You cannot possibly eat gluten without eating something that is processed, period. Every food that contains gluten had to be manufactured from gluten-grains and other ingredients into its final form.

I always tell people that it’s actually very simple to eat a gluten-free diet… if you only eat meat, fruit, vegetables and legumes.

You could even eat some grains, such as rice. While processed, rice in its purest possible form can’t possibly contain any gluten.

The only chance you have of accidentally eating gluten is if you eat anything processed.

This unfortunately includes most restauarant food. Most of it is made from processed ingredients, and you don’t have control over its preparation. Obviously, following the above advice isn’t so easy if you go to a restaurant. You have to make adjustments and do some planning.

But if preparing food at home, and you know how to cook, you don’t have much of an excuse.

Even price is not a concern: Processed food is more expensive per pound, per calorie, than whole food from the produce/meat aisles in their purest available form.

If you need to follow a gluten-free diet, and you’re struggling to maintain it, you may find adherence a lot easier if you go clean and stick to meat, fruit, vegetables, and legumes.

(And of course if you’re vegan, you won’t eat meat. But the other three categories should cover your nutrition needs well. If vegan, I would make sure to include rice.)

Two simple reasons you’re not losing fat

Even after shedding 30 pounds over the years… I used to beat my head into the proverbial wall at times trying to figure out why I couldn’t lose weight, why it seemed like I was gaining weight.

Now, when the scale does tip one way or the other, most of the time I know exactly why weight peels off, why I suddenly gained a few pounds, why the scale’s not moving.

It certainly helps that nowadays I focus more on fueling and refueling workouts and recovery, and it’s not as important how much weight I do or don’t lose. My weight for now is okay, even if it could be better, and as long as I don’t put on a bunch for good I’m not as concerned about it as I am about maintaining my training and health.

Back to the point: When the scale tips, when pounds go off, when they peel off, I have a pretty good idea of why. It often comes down to two important factors aside from mere calories consumed vs calories burned.

If you’re trying to lose fat, and you find (despite your calorie counts making sense) the weight is not coming off or that you’re actually gaining weight, it may come down to two likely culprits.

The Hidden Benefits of Antibiotic Treatment

Yesterday, I had to go on antibiotics for the first time in decades thanks to what apparently is cellulitis in my elbow. As usually happens with these sorts of infections, a weird chain of circumstances likely caused the condition.

A slight cut near my elbow in Vancouver wasn’t totally covered up. Though I cleaned it off regularly, I didn’t bandage it due to its awkward position (band aid style bandages would just fall off), not realizing until after the fact that a knuckle style bandage would have held on fine.

However, that little nick healed after a few days and there were no issues.

Saturday I was doing a bodyweight strength workout that at some point called for a standard elbow plank. I go to the floor and I felt like I leaned on a nerve in my right elbow. It didn’t feel good, but I adjusted and finish that + the workout with no issues.

The tip of my elbow was a bit sore a little later that night, like bursitis (which I’ve had before; that just goes away after you stop doing whatever’s causing it), which I didn’t pay much mind.

But then Sunday morning the elbow was real sore. I already knew then it wasn’t normal bursitis, further confirmed that night when my elbow felt rather warm to the touch… a telltale sign of infection. Knowing I cut that elbow last week, I suspected that bacteria got in and, after bumping it on the elbow plank, managed to work its magic.

I took a mild dose of NSAIDs and waited a couple days hoping maybe my decent immune system would maybe work things out on its own. But by the following night, even though the pain had subsided, the elbow was still warm to the touch, the redness was beginning to spread a bit and I realized I needed medical intervention.

Eating a good diet at destination marathons

With Vancouver I was fortunate that the coastal city had a wealth of sushi options. Sushi rolls were an almost perfect combination of carbohydrates (from the rice) and protein (from the fish, seaweed and soy sauce). Sure, they also had markets with lots of produce, which also helped.

But produce is easy to get in most locales. Rich healthy whole food carb and protein sources… not as much.

Running the Chicago Marathon in October makes this easy since it’s only a few miles down the street. I can cook and eat as typically desired right up to and after the race. To a lesser but still reasonable extent, the nearby Fox Valley Marathon and Milwaukee Lakefront Marathon are close enough that if I ran either of them I could eat normally up to race day.

So, what if I ran a marathon in a more remote locale, where there’s not a lot of stores and restaurants? Or even if it was a major market, what if pretty much every restaurant available served processed and otherwise unhealthy food that wasn’t going to help me stay ready to run?

If you eat eggs, get yourself an egg cooker

 

I eat eggs all the time, and when I make them at home I almost always poach them using a Copper Chef egg cooker I bought at Target for about $20.

The key here is the egg cooker makes preparing a couple eggs super easy and quick. Conventionally, you have to oil up a pan, watch the cooking eggs over flame or a timer, and then dispose of the oil and clean the pan afterward. If you boil eggs, you have to boil water, still watch the time, and then deal with removing the shell while eating.

With an egg cooker, you merely grease the poaching tray by hand (I use olive oil), fill the boil tray with the right amount of water, set the eggs and wait for it to go off. The water evaporates, and the only cleanup is to quickly scrub out the egg tray after use. Cooking two eggs takes perhaps 10 minutes.

This saves time and effort on busy days, if you eat eggs. Consider getting an egg cooker.

Fitness Debriefing After Vancouver 2019

VancouverMedalSitting down and beaten up from the longest run is a great time to take stock of where I’m at with fitness and what I ought to do for next time, even if next time isn’t going to get here for a little while.

I worked hard to prepare for and run Vancouver, and while I improved my endurance and strength in a variety of ways, there’s a number of things that even before the race I knew I wanted and needed to improve.

There’s a lot of goals I have regarding how fast I want to run races, how fast I know I’m capable of running races, and there remains a substantial gap between what I can do and what I want to be able to do… a gap I believe I can substantially close starting even before the beginning of my next training cycle….

When Runners Get Sick

I just spent the last week sick with what might have been the H3N2 variant of the Swine Flu. The office had been fairly sick for a while, and it finally got me last weekend.

I hardly ever get sick anymore. I don’t even get the digestive ailments that used to get me from time to time over the previous years.

I want to call it a testament to my healthy eating and my improved commitment to recovery. But then again, I got sick like everyone else last week, so never mind that.


Coughing up my lungs on Tuesday, I had no idea how long it would take for me to get anywhere near back to normal. The good news on Saturday is my cough subsided substantially and, other than recurring sickness-related digestive issues, and being a little rusty on runs (of course, I broke off training for a few days while sick), I don’t feel bad at all. A couple of colleagues mentioned their flu passed rather quickly, even if the cough loosely hung around for a while. So perhaps it’s the nature of the current illness going around.

In any case, I’d like to think the following approaches helped me quickly unload an unwanted flu, and can help you as well:

The Endurance Diet, and using it to plan a sustainable training diet

Matt Fitzgerald’s book The Endurance Diet is probably the best book on basic nutrition for endurance athletes.

Though Matt has written other books on fueling races and workouts, and maintaining an ideal weight for running, his field research of elite athletes around the world finally put together all the pieces of his knowledge into a system to help you assemble a sustainable, repeatable training diet that will effectively fuel your workout while maintaining a healthy weight and lifestyle.

Losing Fat Without Losing Sleep

An irony of New Year’s Resolutions driving people to diet and hit the gym in January is that winter is probably not the best time to try and burn fat in colder climates.

You have a more difficult time sleeping when hungry, especially if it’s cool or cold. Your body will kick into a sort of overdrive to burn body fat, which revs your circulation up enough to keep you in a state too awake to get to sleep. In fact, if you have issues getting to sleep, you may want to make sure you’re better fed shortly before bed.

But most of you want to lose weight and this is the time to do it because blah blah bathing suit season etc. You don’t want to punt the golden opportunity, and you certainly don’t want to gain weight during the winter when you want or need to lose fat in the long run. Fair enough.

There’s actually a middle ground, and it works especially well if you prefer to train later in the day. The key is intermittent fasting, i.e. not eating for most of the day, then eating all of your food in a limited time window like 6-8 hours.

Now, a myth with intermittent fasting is that it causes you to lose weight in itself. That isn’t necessarily true. You could still overeat for the day in the 6-8 hours you can eat. It’s very easy to pound a frozen pizza, and then a hamburger or something 4-6 hours later, let alone snack on anything in-between, and end up over the line. Even with 16-18 hours of not eating, you could still end up storing extra fat overall.

Given that, it’s still entirely possible to diet effectively and lose weight, while still going to bed each night feeling satiated after a ridiculously sized meal.

The key is to flip the conventional “breakfast like a king, dinner like a pauper” wisdom on its head. This is actually for most a counter-productive way of eating that has been sustained largely out of forced cultural habit. It makes sense to many people (even alleged experts) because that’s always how they’ve eaten.

Basically, even if your last meal of the day isn’t your largest, you want your last meal to be a large meal, one where by the time you go to bed you’re not in any way hungry. You may even want to top it off with a hearty snack right before bed.

Also, as this infers, you probably don’t want to start your limited feeding window at dawn and then eat your last meal around noon or 1pm, going to bed several hours after that meal. You will almost certainly be hungry at bedtime.

You will want to follow a more conventional intermittent fasting window, where you skip breakfast, eat your first meal at lunch, and then eat regularly until before bed. This allows you to fill your stomach close to full before bed and avoid insomnia-producing hunger.

Now, that doesn’t mean your first meal of the day should be the smallest. You can break your intermittent fast at lunch with a large meal as well. Just make sure any meal or snack you eat between lunch and dinner is not too large.

You probably do want to make sure you eat something a few hours after lunch to avoid any hormonal crashes or temptation to binge-eat any garbage at dinner… unless you have a specific reason you’d want to do so (like a special family dinner). Just make sure it’s around the 400-600 calorie range, bigger than a little snack but not quite a full meal.

Just because you can still gain weight intermittent fasting doesn’t mean your body isn’t burning fat during the fasting period. Moderating your diet just makes sure you aren’t piling on more fat than you burn. The fasting period does its job burning fat without food in your stomach. This process revs up your circulation, which you want during the day when you’re awake but mostly sedentary.

By back loading your food intake later in the day, your body can utilize this nutrition for post-workout and overnight recovery, and allow you to relax and sleep.

Vital foods for serious vegan athletes

vegetables and tomatoes on cutting board

Photo by Pixabay on Pexels.com

For a variety of lifestyle and educated reasons I won’t get into, I personally consume meat and other animal products and don’t foreseeably intend to stop. And conversely I have no problem with people choosing to eat vegan, or otherwise vegetarian.

Running is probably one of the easiest forms of fitness to maintain on a vegan diet. Weightlifters and other power-based athletes face substantially greater challenges going vegan. But runners don’t have their strength and power needs. Plus, vegan diets are very carbohydrate rich, which plays right into the needs of endurance athletes.

Still, you need to be wary of your muscles’ and organs’ protein and other nutrient needs. A lot of vegan-common health problems manifest multifold in runners once those runners kick up the volume and intensity. Just because you don’t lift heavy weights doesn’t mean your muscle density isn’t important to your life, let alone your running.

The RDA and other listed mainstream protein requirements are frankly far too low. There’s a variety of political and economic reasons for that, none of which are particularly good for your health. You need more protein than that to live and age well, and most vegans need far more protein than they’re eating.

I set the minimum bar at 0.75 grams per pound of body weight. And if you look at most plant and grain based food, you’ll find reaching that bar is rather difficult.

There are certain foods that are very important to the health of serious vegan athletes.

Beans and legumes. These plant based foods provide the most protein, and a variety of other nutrients. Whether or not you’re a believer in combining proteins (e.g. eating beans with rice), beans in themselves contain a ton of potassium and protein. Just make sure to soak them properly to minimize digestive gas.

Some people swear by lentils, but not everyone digests them well. I’ve always had trouble digesting lentils. Barring that, they too are a great protein source.

Avocados, potatoes and bananas, aka the potassium monsters. Most people vegan or not don’t get enough potassium. The benchmark is 3000-4500 mg per day, depending on who you talk to, and the typical processed food rich Western diet won’t get you close.

Meat it turns out has a good share of potassium, but surprisingly many plant-based foods don’t provide much more than a similar serving of meat.

Avocados and bananas are convenient, useful potassium bombs. One avocado provides 800-1000 mg. Each banana gives you about 400 mg. But potatoes are the motherlode. A small potato can give you 600-700 mg. Cut up and eat three of them, and that’s around 2000 mg right there.

It’s little wonder so many people swear by potatoes. Famous magician Penn Jillette lost over 100 lbs subsisting largely on potatoes, which provided virtually all the nutrients his shrinking body needed. They are a calorie-dense wonder starch.

People love sweet potatoes and they’re totally fine, but they’re a bit harder to find. Conventional potatoes do the trick just fine.

If you can eat gluten, bagels. Most breads are not worth anyone’s time. But bagels are as dense and protein-rich a form of bread as you will find.

Yes, obviously for vegans there is concern that some bagels are made with egg or honey products, which are of course not vegan. If you want to try bagels and aren’t acutely aware of the source, read your labels and make sure no animal products are involved. To my knowledge, most bagels should be clear on that front. But definitely double check.

Provided they work for you… compact and calorie rich, one or two bagels on their own will provide enough energy for your longest workouts… let alone if you tack on any toppings (I’m guessing as vegans that cream cheese or butter isn’t among them). I’m a sucker for crunchy peanut butter and fruit preserves (… if there’s no corn syrup or other additives! Whole Foods has varieties of both that are free of most typical additives, that are worth the extra cost).

Bonus: Ugali. The great Kenyan runners live on two food staples. One is not vegan: Milk infused tea. They drink it after every run. The other, however, is very vegan. Ugali is nothing more than finely ground flour (often cornmeal) and water mixed over boiling heat to create a thick mashed-potato-like porridge. The Kenyans eat a ton of ugali. And their runners crush almost every other elite distance runner in the world at major long distance events.

Ugali is cooked like the love child of rice and oatmeal. You add 2 cups of water for every 1 cup of flour. You boil it, mash out any lumps as it cooks, and then thicken or thin it using more water or flour as desired before serving. Cooking it takes about 10-15 minutes. The nutritional profile is similar to rice, except with a little bit more potassium.

If you train a lot, this is one of the quickest deliveries of large quantities of glycogen-producing carbohydrate you can ingest. This is a great dish to eat before or after tough training days. The Kenyans are not kidding.

———-

Yeah, I’m not vegan, and I’m in no hurry to adopt the lifestyle.

Still, it can be done without sentencing to death your muscle tone and (for men) your testosterone levels. There are foods that will allow you to take full advantage of your training. Eat them.

Three Valuable Tips for Beginning Runners

1. You should run as slow as you can

You absolutely need to run slow. Slower than you think. Run as slow as you need to in order to keep running. As a newcomer to running, you will struggle to run for any amount of distance, and chances are likely you will quit early unless you first focus on running far as slowly as you can get away with.

A parallel: Competitive walking has a rigid set of rules that constitute what exactly constitutes a walk, and it’s a good guide for the minimum of what you need to do for your movement to qualify as a run.

A key point in race walking is that your back foot must be on the ground until your front foot plants on the ground.

Conversely, if your back foot comes up before your front foot impacts the ground, then you are technically running. See how slowly you can get away with safely doing this, and you may be surprised how slowly you are allowed to run.

2. Take each step as soft and easy as you can

Another key reason you want to run slow is to make it easier for you to run without having to hit the ground hard.

A telltale sign that a runner is outrunning his/her normal capabilities is that their feet hit the ground hard and loud. This isn’t just aesthetically displeasing, but it’s not healthy. You’re jarring your joints, muscles and ligaments all the way up the chain from your feet up into your core, and risking long term injury. In fact, this is largely where common runner ailments like shin splints and IT band pain come from. You basically just stress those parts of your body until they hurt.

In dance and some theatre circles, performers get taught how to step as softly as they can. There’s usually no real method taught to this, but performers often work at it until they develop the locus of control to step softly. I guess it incidentally helped that I studied theatre and dance before becoming a serious runner, as learning this inadvertently, eventually helped me develop better running form.

But you don’t need to dance or do theatre to learn to run soft and easy. Stand up. Find some open space. Take a step forward as softly as you can. Take another step forward as softly as you can. Repeat. Take your time and relax while repeating this. You may find that your body naturally moves and adjusts with you. Eventually your body just knows how to move to comfortably make it work. It also probably feels silly to do, but work with it.

Now try to do it quickly, but stay as relaxed as possible. Do it consistently and quickly enough, and all of a sudden you’re running that way. It may not be fast or intense, but it works.

The home run trot that I previously advocated is basically just this. It’s exactly what baseball players are doing. They’re just running as easy and comfortable as possible. Their feet are definitely not slamming into the ground.

3. Eat something with protein within an hour after every run

Recovery is something even experienced runners aren’t great at doing. Most don’t think at all about taking in nutrition within two hours of running, or realize that the half hour after running is a valuable window for refueling the body.

While carbohydrates may be valuable for glycogen restoration, what you do need for sure is protein. You just did a bit of damage to your muscles, and they need protein to rebuild. Consume at least 15-30g of protein.

I’m not saying you should pig out. Just eat a protein bar, some nuts or seeds, or drink a glass of milk, if nothing else. If you are in fact planning to eat a meal like breakfast or dinner right after running, great. Mission accomplished.

I can get into all the science as to why processed junk doesn’t help you as much as whole food, but in a nutshell you’re better off eating something healthy. If you’re in a bind and options are limited, then eat what you must. But given the option, try to eat whole foods in as close to their natural form as you can.

How well you bounce back between workouts is largely a function of how you recover. What you eat or drink soon after the run matters.

The Control Rest Day Baseline, and using it to successfully carb cycle

Yesterday with the day off I did nothing, in terms of training. No running, no strength work, nothing particularly strenuous. I actually drove to get coffee, since I had vehicle-related errands to run that day. I did a minimum of walking… not easy to do in Chicago when you live in Wrigleyville and you do most of your business on foot.

Okay, big deal, just a rest day, right? Well….

… it had been a while since I’ve taken stock of my working basal metabolic rate (BMR). Your BMR is the rate at which you would burn calories in a day if you did nothing but lay or sit there. For men my size and age, this is somewhere around 1650-1700 calories.

You do more than sit around all day, so to find your baseline calorie burn you multiply that BMR by a standard multiplier.

  • Sedentary people who drive everywhere and never exercise can use 1.2 as their multiplier. You multiply your basic BMR by 1.2 to get your actual basal metabolic rate.
  • If you get any exercise once or twice a week, or you walk to get around everyday, your multiplier may be closer to 1.3.
  • If you work out every day it may be as low as 1.5 or as high as 2.0, depending on what you do for workouts.

Of course, I can’t just set my baseline at 1700 calories multiplied by a standard multiplier. My daily activity can vary widely, as a Chicago local who gets around on foot and runs a lot. Even if I don’t run, I may walk anywhere from 20ish minutes a day to several miles, and there’s no rhyme or reason relative to my training as to how much walking I do. Plus, this completely ignores strength training and any other physical activity.

I’ve had days where, with identical training (or lack thereof), I’ve burned anywhere from 2100 calories to over 4000. So, plugging my estimated general activity into a BMR tool and spitting out a number isn’t necessarily going to help me.


I still want to get enough to eat, while not overeating. I still do have tracker data that shows an average weekly calorie burn, which is around 3000 calories per day during training. But there’s more to it than that:

Why is my resting heart rate going up?

 

When I first got my Fitbit tracker, back when I first began seriously training as an endurance runner, it initially showed my resting heart rate’s (RHR) beats per minute (BPM) in the high 60’s.

As I continued training, my resting heart rate came down and settled around the high 50’s. Sometimes it would drift up, but often it came back down to around that number.

I noticed that generally it would increase during times of substantial stress, and that it would decrease with proper rest and exercise.

Suddenly, during the late summer and early fall, my resting heart rate started slowly climbing. Suddenly it settled into the mid 60’s and nothing I thought to do could bring it down. Resting more didn’t help. Eating more or less or better didn’t help. Exercising more or less didn’t seem to help.

At some point, not at the same time as last year, it began to come down again and settled around the high 50’s, low 60’s.

And now my resting heart rate’s risen again. It had settled around 65 for several weeks, and nothing I’ve done has gotten it to move. Now suddenly it’s climbed to 68… but at the same time I think I realized what has caused it to increase.

It’s not a lack of rest: I’ve actually slept rather well, and I haven’t trained at anywhere near the volume I’ve trained before. Outside of residual soreness from workouts and Sunday’s cross country race I haven’t been all that sore, tired or hurting. My energy levels by and large have been great.

It’s not a lack of exercise. I’ve now ramped back up to about 25-30 miles per week, and I’ve done multiple speedwork sessions as well as some long runs. The only difference from my last training cycle is I’ve taken days off and not held myself to much of a strict training schedule.

It’s not even post-marathon weight gain. I’ve had my RHR go lower even after gaining weight, and I’ve had it rise after losing weight. There’s not much correlation between my resting heart rate and my current weight.

It’s not illness. I haven’t been sick and I’m not sick right now. I don’t feel any passive symptoms like unusual tiredness or soreness. I’m in good health on that front.

It’s two things.

Practicing fueling during marathon training

A lot of people struggle with fueling during a marathon because they aren’t used to running with food or drink (beyond water or maybe Gatorade) in their stomach.

I have a fairly strong running stomach.
