VDOT is a running performance score based on scientific research developed by legendary coach Dr. Jack Daniels. It gives you a number based on how fast you run. This number can be compared with other people’s results, letting you know where you stand in the running community.

VDOT is the most objective and scientific running performance score available for free. This includes a scoring algorithm that calculates scores based on age, sex, race, speed, and distance. A score of around 60 means that you are in the average range of all runners, while a score of around 80 means that you are a top performer.
