Based on former Olympian, author, and legendary running coach Jack Daniels’ exercise science principles, the methodology not only benefits runners of all ages and abilities when it comes to improving their running fitness but it also serves as the best measure of running economy across a variety of runners and events, making it an ideal way to compare performances. High-school, college, Olympic and non-elite runners have all trained, ran, and succeeded with the VDOT methodology. -”Dr. Jack Daniels has had a bigger influence on training-for-running than anyone. He might be considered the Albert Einstein of the sport." - Runner’s World Magazine
