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. 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).

Verdict
The clearest difference is ads: VDOT Running Calculator at none against Pace's shown. VDOT Running Calculator also leads on ratings volume (1.6K vs 386) and iOS requirement (15.0 vs 18.6). Pace's advantage is update cadence (every 6 weeks vs every 4 months). On price, rating, review sentiment and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. VDOT Running Calculator sells 1 one-off in-app purchase and Pace sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
VDOT Running Calculator holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 1.6K and 386 respectively. Written reviews complicate that: 74% of VDOT Running Calculator's written reviews are positive against 75% of Pace's, so the app with the better star average is not the one people write more warmly about.
VDOT Running Calculator ships an update every 4 months, Pace every 6 weeks. The most recent releases landed on November 1, 2026 and October 27, 2026 respectively.
