Dr. Phil Maffetone, creator of the Maffetone Method, has a simple approach to running: run all of your training miles at your true Maximum Aerobic Function (a formula Maffetone created) and you'll get faster over time, with a lower risk for injury. His 2010 title, The Big Book of Endurance Training and Racing, co-written with Mark Allen, is considered by many to be one of the most comprehensive training manuals on the sport. Recently published, The Endurance Handbook is a follow-up to the Big Book that provides new insights and nutrition information on how to run "fat adapted" by following a low-carb, high-fat diet, which will appeal to Paleo and keto runners.
