Establishing A Running Foundation

Written by: Matt Fitzgerald

The top training priority of every new runner should be to establish a solid foundation for future development as a runner. How is this done? The physiological foundation for running performance has two components: aerobic fitness and neuromuscular fitness. You know what aerobic fitness is: the ability to generate large amounts of energy efficiently with oxygen taken from the environment. Neuromuscular fitness is the ability to generate a high level of stride power in an energy-efficient manner.
When you first take up running, you need to focus your training on developing these characteristics in a manner that is appropriate for a person starting at square one. Veteran runners, who have already developed a solid foundation of aerobic and neuromuscular fitness, need to focus their training instead on advanced types of workouts that build on this foundation and on “specific-endurance” workouts that combine high aerobic and neuromuscular demands and thereby simulate race intensities.
Aerobic Training 101
The best way to lay a foundation of aerobic fitness is quite simple: Perform a gradually and steadily increasing amount of running at a comfortable pace. Start by running every other day and work toward running six or seven days a week. Start with short (15-20 minutes) runs and slowly increase the duration of your average run to 45 minutes or so. Do one “long run” per week on Saturday or Sunday. Keep increasing the duration of this run until it’s long enough to carry you to the finish line of the longest events you care to do.
Total running volume is the single best predictor of running fitness. That’s why the vast majority of elite runners work out twice a day and run upwards of 100 miles per week. You can improve as a runner for years simply by increasing the amount of easy running you do each week until you reach the maximum level you’re comfortable with (even if it’s nowhere near 100 miles per week!). Sure, you can mix in some more advanced types of aerobic training, such as threshold runs, which consist of extended segments (10 to 30 minutes) of moderately hard running between a warmup and cooldown, but as a beginner you should keep this type of training to a minimum and prioritize sheer volume.
Neuromuscular Training
If the best way to build a foundation of aerobic fitness is to go long and slow, the best way to build a foundation of neuromuscular fitness is to do very short, very fast efforts such as speed intervals (e.g. 6 x 300-meter relaxed sprints a track), fartlek intervals (30-60-second hard efforts sprinkled throughout an otherwise easy run) and steep hill sprints.
Start with steep hill sprints. These short, maximum-intensity efforts against gravity provide two key benefits. First, they strengthen all of the running muscles, making you much less injury-prone. They also increase the power and efficiency of the stride, enabling you to cover more ground with each stride with less energy in race circumstances. These are significant benefits from a training method that takes very little time and is fun to do.
If you have never done a steep hill sprint before, you should not leap into a set of 10 of steep hill sprints the very first time you try them. These efforts place a tremendous stress on the muscles and connective tissues. Thus, the careless beginner is at some risk of suffering a muscle or tendon strain or another such acute injury when performing steep hill sprints. Once your legs have adapted to the stress they impose, steep hill sprints actually protect against injury. But you must proceed with caution until you get over the hump of those early adaptations.
Your very first session, performed after completion of an easy run, should consist of just one or two eight-second sprints on a steep incline of approximately six percent. If you don’t know what a six-percent gradient looks or feels like, get on a treadmill and adjust the incline to six percent. Then find a hill that matches it.
Your first session will stimulate physiological adaptations that serve to better protect your muscles and connective tissues from damage in your next session. Known to exercise scientists as the “repeated bout effect,” these adaptations occur very quickly. If you do your first steep hill sprints on a Monday, you will be ready to do another session by Thursday—and you will almost certainly experience less muscle soreness after this second session.
Thanks to the repeated bout effect, you can increase your steep hill sprint training fairly rapidly and thereby develop strength and stride power quickly. First, increase the number of eight-second sprints you perform by two per session per week. Once you’re doing eight to 10 sprints, move to 10-second sprints and a steeper, eight-percent incline. After a few more weeks, advance to 12-second sprints on a 10-percent incline. Always allow yourself the opportunity to recovery fully between individual sprints within a session. In other words, rest long enough so that you are able to cover just as much distance in the next sprint as you did in the previous one. Simply walking back down the hill you just ran up should do the trick, but if you need more time, take it.
Most runners will achieve as much strength and power improvement as they can get by doing 10 to 12 hill sprints of 12 seconds each, twice a week. Once you have reached this level and have stopped gaining strength and power, you can cut back to one set of 10 to 12 hill sprints per week. This level of maximum power training will suffice to maintain your gains through the remainder of the training cycle.
Taking the Long View
As the seasons and years go by, assuming you train sensibly, your training should evolve first by adding layer upon layer to this foundation of aerobic and neuromuscular fitness through increasing mileage and more challenging aerobic workouts, including longer long runs, and also through more challenging high-intensity neuromuscular training. As these types of training begin to reach a point of diminishing returns, gradually shift your focus toward specific-endurance training for your primary race event.
The longer you continue training for competitive performance in the sport of distance running, the more your overall training mix should move away from general training at the extremes and the more it should focus on specific endurance.
