Plan Description

80/20 Endurance

This four-week indoor training plan is specially designed to help runners develop a more efficient stride. Though originally intended as a way for runners make the best of the current health crisis, you can use it whenever you're taking a break from race-focused training and wish to prioritize form over fitness. Based on the latest science and on current elite-level best practices, the plan has the following elements:

Drills and Plyometrics: Technique drills and plyometric exercises (i.e. jumping exercises) improve running form by developing more efficient movement patterns and enhancing the springlike quality of the legs.

Functional Strength Training: A run-specific strength program contributes to a better stride by enhancing joint stability, thereby eliminating energy waste during running.

High-Intensity Hill Repetitions: Running fast is a proven booster of running economy. Meanwhile, running uphill tends to encourage more "textbook" form, especially when done mindfully. Put the two together and you've got a powerful tool for building a better stride.

Barefoot Running: Most runners overstride when wearing shoes. No runner overstrides barefoot. Doing a bit of running without shoes is therefore a good way to correct overstriding. It also strengthens the feet and lower legs, making them more effective contributors to the stride.

Cadence Runs: Each runner has a natural cadence, or step rate, which tends to automatically increase as fitness and form improve. While it's generally best not to interfere with this process, research has shown that consciously increasing step rate improves biomechanics in runners prone to injury. Hence, this plan includes one high-cadence run per week.

Target Athlete

This plan in intended for experienced runners with a solid current fitness base. You should be able to comfortably run for at least 45 minutes before you start the plan.

80/20 Endurance

80/20 Endurance

80/20 Endurance is the creation of Matt Fitzgerald and David Warden. Based on the breakthrough books 80/20 Running and 80/20 Triathlon, runners, triathletes, and other endurance athletes improve the most when they consistently do 80 percent of their training at low intensity and the other 20 percent high intensity. The typical endurance athlete spends only 50-70 percent their total training time at low intensity. The solution? An 80/20 training plan that ensures the optimal intensity balance.
