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.

Thanks to over 50 years of scientific research conducted by legendary coach Dr. Jack Daniels, runners and coaches can quickly determine appropriate training paces, equate race performances and adjust for heat and altitude.

• 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).

Great but it does bin data all the time

I wish it would remember previous data. It’s a pain to have to re enter data every time you open the app.

A very useful tool which if you are using the Daniels system for training. My only complaint is that I wish it would remember your VDOT, as every time you go into it you have to input your race time to get you VDOT. I'm also puzzled as to why after entering a race result, that same race is then predicted as a few seconds slower!

Developer Response ,

Jin, I'd recommend using our VDOT Calendar if you are using the calculator regularly. You can find this free app by viewing our other products.
