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.
