A new 10K strategy, and a 2019 Mardi Gras Chaser 10K race recap

Yesterday I ran the Mardi Gras Chaser 10K on the Chicago Lakefront Trail, experimenting with a different race strategy based on my training. It worked remarkably well and at 52:40 I PR’d by about 32 seconds.

In fact, given better training and circumstances, I could have possibly run this race another minute or more faster. To PR so well despite no specific endurance speed workouts during the past month, despite extreme cold setting back some workouts, was pretty remarkable. I came into this race a little more speed-rusty than I would have liked.

This strategy allowed me to run probably the most evenly paced race-level effort I’ve ever ran. I may have run one or two better races in my time, but this was the most sustainably strong and even effort I’ve given over any full race distance beyond 5K.

I hit the turnaround (the course was an even out and back) at 26:24, meaning I ran the last half of the race at 26:16, a slight negative split.

So how did I do it?

BACKGROUND

Throughout the (better parts of) winter I had done some 10K-specific training, most specifically The McMillan 10K Workout. That workout is simple: 3 long cruise reps of 2 miles each at 10K pace, with a few minutes of active recovery between. If you manage your desired pace during the reps, you can probably nail the pace in your 10K.

I did the workout every fortnight or so during the early winter, before the F3 Half, the start of my Vancouver Marathon training, and the brutality of Chiberia all intervened. Even then, conditions on the track were often icy enough to slow my desired pace, so I had to focus more on fast cadence and not worry as much about splits.

Other than that, I did no real tempo running outside of the races I ran (Tour De Trails, and the F3). Thanks to the Half and the weather, I went about a full month without doing the workout. Even if I felt confident about my ability to hit a 10K tempo, coming into this 10K I wasn’t convinced I could hold anything close to it for a full, uninterrupted 6+ miles.

THE PLAN

MardiGrasChaser10K

The 2019 Mardi Gras Chaser 10K course. (The organizers ended up nixing the shortcut on the way back at the sharp Montrose turn, so it was an equi-distant out and back course.)

The course was a simple setup, with two tables along the course serving as double aid-stations: The first table out was the 1st and 4th water station, and the second table was the 2nd and 3rd water station.

Some approximate measurements indicated the tables were about 1.3 miles apart, with the 1st table being about 1.28 miles from the start line… meaning it was also 1.28 miles from the finish.

By simple math and inductive reasoning, knowing the turnaround would be exactly 5K away (3.11 miles), the turnaround was 0.53 miles from the 2nd table, meaning about 1.06 miles of running from station 2 to station 3.

Despite knowing I could comfortably hold an 8:25ish pace over 2 miles, I didn’t know if I could sustain that pace over 6.21 miles without having trained at speed at all over the last month.

I decided to hedge my potential lack of ability to maintain pace over the distance by turning the race into a long version of the McMillan workout:

Run at race pace until reaching Aid Station 2. I planned to start at race pace, moving my feet light and quick and sticking with it for the 20 or so minutes it would take to reach the 2nd aid station, about 2.6 miles away. This was just a bit longer than a McMillan rep, but from my experience I always finished those workout reps strong, and maintaining the cadence/pace for an extra 3-4 minutes wasn’t that big a deal.

I would blow past the 1st water station and keep moving. The plan was to get to the 2nd aid station before I would…

… slow down, take fluid, and run easy for 1 minute. Previously in races, I would either try to keep pace while taking fluid at stations, or slow outright to a walk and take it easy until I drank what I needed before speeding back up.

I had never tried the middle ground, and I was going to. Slow down to a regular running pace, something like 10-11 minutes/mile, while taking and drinking water. Even after finishing, I would run at this pace until a minute had passed, and then resume running at pace.

This was very similar to the workout, as during my recovery intervals in the workout I didn’t stop. Instead I ran easy around the track and kept moving. This would basically be a slightly higher intensity of the same thing. Once the intervals were finished I was always ready to go again at full speed, and I felt I’d be able to do the same here.

Resume race pace, and keep it until Aid Station 4. This particular “rep” would not be as long as the first, at about 2.3 miles or so (after the recovery interval) instead of 2.6. And that was fine, because fatigue should begin to set in down the stretch, and it would help to finish the 2nd stretch a little more quickly than the 1st.

I’d circle the turnaround, skip past the 3rd aid station, and plan to slow for fluid at the 4th and final station.

Again, slow to a regular run for 1 minute at Aid Station 4 while taking fluid. I would repeat the process for fluid, finish and make sure I got in one minute of easy running, before…

… resume race pace, and finish the race strong. At this point, there should only be about 1.1 miles left, far less of a chunk to run at race cadence. And that never minds whatever kick I could give at the end.

THE PLAN WORKED!

I stuck to the plan, to the letter, up until the 4th aid station, where I felt strong enough that, after a moment to take fluid, I just resumed race pace without any more rest, and finished the race from there. That might have shaved a few seconds off of what was ultimately a sizable P.R., so no regrets about that decision.

The whole race felt surprisingly easy. This wasn’t entirely because of the plan itself: I did focus more on a light, quick cadence and not falling into the trap of straining or overstriding for extra pace. That kept me from unduly wearing myself out in the early and middle miles.

But the plan also gave my effort clear boundaries. I knew that, no matter how badly things were feeling, I only had to get to the 2nd or 4th aid station before I could relax a bit. I knew my training had prepared me for 20 minutes of solid race-pace effort at a time, and for multiple reps of that same 20 minute effort.

It may not be how most people run a race, but this approach gave me the ability to run a better race than I otherwise would have.

DO I RECOMMEND THIS RACE PLAN?

This is honestly a perfect approach for any race where you don’t feel comfortable with your ability to run the entire race strong, from the 5K to the marathon. By building in recovery intervals around your visits to key aid stations, you can ensure you maintain an even, strong race effort to the finish.

There are two key caveats:

1) Obviously, you need to have the aerobic endurance to run the desired distance.

I consistently run 4-7 miles in workouts, plus do longer runs beyond that distance, plus on speedwork days (between warmups, recovery runs and the actual workout) I may log over 10 miles. You don’t need to run that much to do well in any distance below the Half… but no plan will work for you if you don’t safely run several days a week, and you ideally should run a weekly mileage of at least 3 times the race distance.

2) You need to do workouts where you practice this approach.

This plan worked for me because I was experienced with the McMillan 10K workout, which basically follows the same pattern. The plan obviously is based on the workout.

If you’re not used to running at your desired pace for at least a couple miles, this plan is going to be very difficult.

The plan can be adapted to where you slow to a regular run for one minute at every aid station, which allows for about 1.2-1.4 miles at your pace. But you still need to be able to run at race pace for reps lasting that distance, several times a workout.

However, that’s still a lot easier than trying to hold such a pace for an entire race without stopping… especially if you’re not used to doing it.

IN CONCLUSION

While ideally I can run races without having to do this every time… this is a fine fallback option for any race where the confidence to run the full distance at pace isn’t totally there.

And it can be adjusted for any distance: For example, I could decide to run a 5K as two 2500ish meter reps, taking fluid at the one water station and going easy for one minute before picking it back up and finishing strong. Or I could run a marathon as a series of very long 3-4 mile M-pace reps, taking 2-4 minutes of easy running (and, as needed, hard fueling) at key aid stations.

Even if your race has no aid stations or they’re spaced very far apart, you could bring hydration and just decide to go a set time period, like 20 minutes… then slow to a regular run, drink from your stores and go easy for 1-2 minutes before resuming for another 20 minutes. In fact, if you carry hydration you could do this even if the race has aid stations. You decide on your own how far to go during each “rep”.

Who knows… maybe I’ll do this at Vancouver this May. Or Chicago Marathon this October. Or next month at the Lakefront 10 Miler. Or maybe I feel much stronger for those races and don’t do it at all.

But The Plan worked! And now I have a proven, workable fallback plan for every race where I don’t feel fully confident in my ability to race.

Strategic approaches to racing the 10 Miler

While not as popular elsewhere, the 10 Mile race distance is somewhat popular in the Midwest, especially in Chicagoland. Chicago alone has two major 10 Mile races, the Lakefront 10 in April (my favorite race) and the Soldier Field 10 in May. Several others (Quarryman Challenge and Fort2Base) are annually held in the suburbs with high turnout. There’s also the 15K (9.32 miles), the close metric cousin of the 10 Miler, and the Hot Chocolate 15K is another popular Chicago race held in November.

Because the distance is not popular like the 5K, 10K, half and full marathon distances, there’s not a lot of strategic material on how to race the distance. The next shortest popular distance is the 10K, which is over 6K shorter. Most runners approach it similar to a half marathon, even though the distance is about 5K shorter and experienced runners are probably leaving a bit in the tank.

I have run 10 Milers mostly as a long distance run (as the half-marathon runners do), and I ran my last 10 Miler as a marathon-pace tune up. However, having given it some research and thought, I have settled on two strategies for running the 10 Miler

Strategy One: The Hadfield Method

Jenny Hadfield crafted a smart approach for marathoners and half marathoners running their first race, and I think it translates well to the 10 Mile distance for most people. Along with new runners to the 10 Miler, Strategy One probably best for experienced runners who put in less than 65 miles a week.

The Hadfield Strategy, in short:

  • You run the first 60% or so of the race at an easy pace to comfortably maintain.
  • You run the next 30% or so at more of a comfortably hard tempo
  • The final 10% is closer to a max effort for whatever you have left.
  • It’s a great strategy in that it doesn’t necessarily have to be built around pace, but around your perceived effort.

If you’re not too fixed on finding goal paces, you are welcome to stop there. Just run the first 6 miles easy, the next 2-3 miles comfortably hard (if you’re running a 15K, it’s 2 miles), then go for it in the final mile.

However, for more experienced runners, I’m more than willing to recommend something closer to actual paces for Hadfielding the 10 Miler:

  1. Start at half marathon pace, and hold this pace until Mile 6.
  2. At Mile 6, pick it up to a 10K effort. If you can’t hit your 10K pace, then 10K level effort is enough. You basically want to treat this section like the last half of a 10K, except don’t kick or accelerate as you would in mile 5. Just pick it up as if you were trying to run an even 10K with a slight negative split.
  3. At mile 9 (or if this is a 15K, mile 8), kick it up to at least 5K pace or effort. If you have it in you to treat the final mile like a mile time trial or 3000 meter race, then go. But 5K effort is completely acceptable. Get to the pace that you can carry in that final mile to the finish line. (Side note for Lakefront 10 runners: I’d maybe keep it exclusively at 5K effort, because you still have to climb and descend Cricket Hill at the end of the race.)
  4. Once you see the finish line and know you can get there, kick.

Strategy Two: 10 Mile pace, defined.

The other approach is of course to run the entire race at a chosen, suitable pace as you would any other race.

But what would be an ideal 10 Mile pace? Much like an ideal half marathon pace, it’s an intensity reserved for only the most well-trained, durable runners. This is why, as previously implied, it should only be attempted by experienced runners who consistently log more than 65 miles per week.

Top half marathoners race at about their lactate threshold intensity, which most schools of thought refer to as Tempo, Cruise or Threshold pace.

It’s around 85% of your max, and the reason most recommend a slower half marathon pace for most is because most can’t sustain that kind of effort for the time it takes them to cover 13.1 miles. An elite runner can clear 13.1 in a bit over an hour, so it’s not as taxing for them.

An optimal 10 Mile pace is around the high end of Threshold tempo, right before drifting into 10K territory. Most runners can’t sustain that effort for 75-100 minutes, but a fast runner that can clear 10 miles in under an hour can do so easily.

The key gauge is the longest period you can manageably sustain an uninterrupted threshold effort run. If you can’t go at least 6.5 miles straight at that intensity, asking you to do it for 10 is probably too much. Hence the previous Hadfieldian strategy recommending you go by feel, start easy and basically assure yourself an excellent negative split.

A cracky common-sense method for estimating your optimum 10 Miler pace:

Add your half marathon pace and your 10K pace together, then divide by two.

The challenge, similar to a half or full marathon, is holding that pace for 10 miles. A half marathon effort is comfortably hard but somewhat easily sustainable. This pace at its hardest is more like a tempo run you’d only hold for 60 minutes max.

If you have 9-12 weeks training time before the race, you can gauge your actual 10 Miler pace through trial and error testing (and of course make sure you don’t have any speedwork or long runs within 2 days of doing the below):

  1. Pick a comfortably hard pace you think you can maintain for an hour, and run an uninterrupted tempo run at that pace for as long as you can. Aim for an hour minimum. IMPORTANT: If your heart rate reaches 90% of your max or your known 10K effort, stop the workout immediately and note your distance traveled.
  2. If you find you can’t run at least 6.5 miles at that pace, wait a week and try again at a pace 5 seconds per mile slower (3 seconds per kilometer). Again, run for at least an hour and aim for 6.5 miles without distress or other trouble. And again, if you miss the mark, repeat a week later with a pace 5 seconds per mile (3/km) slower.
  3. If after 3 tries you haven’t been able to finish 6.5 miles… just use your half marathon pace as your 10 Mile pace.

That is for all intents and purposes your 10 Mile pace. Train accordingly with that pace until race day.


… now how do you train for a 10 Miler, you may ask?

I’ll get to that at some point, but I’ll leave it at that for now.
