Science And Evidence-Based Training Method (VDOT).

VDOT is a measure of your current running fitness.

After examining the performances and measured VO2max and VO2 sub-max (running economy) of runners (spanning several decades) over a wide range of speeds and race distances, it was clear that runners of equal race times often did not have equal, or even near-equal VO2max values. It also became clear that running economy was as important as VO2max in evaluating performance.

VDOT values are associated with all endurance-race times (800-marathon), which is clearly an ideal way to compare performances over a variety of events and runners of a variety of performances.

Thousands of coaches, and millions of athletes worldwide have relied on VDOT, a proven training methodology popularized in Daniels’ Running Formula, and based on over 50-years of scientific research. Because the methodology is based on exercise science principles and human physiology, runners of all ages and both recreational and elite runners all benefit the same when it comes to improving running fitness.

- "If the best measure of good training techniques is staying power, then Jack Daniels has set the gold standard. I continue to employ his techniques years after meeting him in 1980." - Joan Benoit Samuelson
