The official VDOT Running Calculator, designed by Dr. Jack Daniels - named World's Best Running Coach by Runner's World Magazine - and the team at VDOT O2.

Features: • Calculate time, distance and race paces • Calculate your current training paces • Calculate and compare the equivalent performances of a race result at other distances • Calculate the effect of temperature or altitude on training and race paces What's Your VDOT? VDOT is a measure of your current running ability. It assigns a score to all running performances, let's you determine your current training paces, and equates a race time in one distance to another. For instance, you can compare your VDOT score from a recent 5k result to a friend's score who just ran a half marathon. Who won? What VDOT Level Have You Reached? Input a race result or estimated performance and learn what score it reaches on the VDOT scale. Enter all your past performances to see which race result scores the highest. There are 10 levels starting at Beginner - White (Female: 34.3, Male: 36.8) all the way up to Professional - Gold (Female: 71, Male: 80).
