VDOT O2 1.59

Unlike other running apps, VDOT O2 determines your proper training and race paces, based on the science and formulas of legendary coach Dr. Jack Daniels.

Now runners can create workouts, or get them published by a coach, and sync to Garmin for real-time pacing guidance. With the result of a recent competition runners can update their training paces and see their equivalent race performances across any distance.

Given that runners with identical VO2max values may have differences in running economy, biomechanics and mental toughness, we conclude that VDOT is a better value from which to assess fitness and determine proper training paces.
