Intermediate Marathon Training Plan

This 18-week Intermediate Marathon Training Plan is tailored specifically for runners with some running experience who wish to challenge themselves by running a marathon. The schedule balances different running intensities to ensure that endurance, speed, and efficiency are increased, starting with easy runs, interval sessions, and moderate-paced runs, gradually increasing mileage over 18 weeks while emphasizing rest and recovery as key elements for avoiding injuries and improving overall performance.

As weeks pass, tempo runs become an essential component of training. These runs should be performed slightly faster than race to build cardiovascular and muscular strength while increasing threshold levels. Interval sessions, on the other hand, help develop aerobic capacity, assisting runners to maintain a marathon pace for all 26.2 miles. Furthermore, this plan includes “shakeout runs”, short distances at slower paces, specifically during tapering phases such as the last week of tapering. These programs aim to keep muscles engaged without leading to fatigue, helping runners prepare for race day with long runs that reach 20 miles and beyond. On race day, participants should feel mentally and physically prepared for their marathon distance journey.

Remember, this plan is only meant as an approximate guide, and any individual using it should tailor it based on their needs, goals, and feedback from their body. Before beginning any fitness regimen, it would be prudent to consult a fitness professional or doctor first.
