Plan Description

This "Ancestral Athlete" marathon plan is based on the healthy training concepts that Ben Greenfield teaches in his book "Beyond Training" and also in the article at

It relies on "underground" training tactics, high intensity interval training and a natural physically active lifestyle to allow for optimum endurance building and marathon preparation without doing lasting damage to the body.

This 20 week (5 month) plan is perfect if you are a beginner to advanced marathoner who is limited on time (6-10 hours per week), want to get the most bang for your buck out of training, and also want to ensure you stay completely healthy in the process of pursuing your endurance goals.
