Plan Description

Welcome to the 3 Sports Science Marathon 20-week Base and Build Phases Training Plan. This 20-week plan is for preparing for a marathon or increasing your overall aerobic endurance. This plan assumes you have a low to moderate running fitness and fits well early in the base period of an Annual Training Plan. This plan is written for you to utilize running power, heart rate, pace, or rate of perceived exertion (RPE) as your pacing guide. The general outline of the plan is as follows:

Monday – Day off/Yoga
Tuesday – Short endurance run
Wednesday – Tempo run
Thursday - Short endurance run
Friday – Day off
Saturday – Upper endurance run
Sunday – Long run

This entire program is written by Dr. Chris Myers who has a Ph.D. in Exercise Physiology, specializing in endurance physiology, and has a background in sports nutrition. He is the Head Coach and founder of 3 Sports Science, USAC Level 1 Coach, USA Swimming Level 4, USAT Level IIE, and IMU Certified coach.
