Both calculators run independently — change the inputs on either side to compare results.

Running Pace Calculator

Calculate your running pace per mile (or per kilometer) given total time and distance covered. Use it to track training-run efficiency, set race goal paces, and compare your current performance against benchmark times for 5K, 10K, half-marathon, or marathon distances.

VO2 Max Calculator

Estimate your VO2 max — the maximum rate at which your body can take up and use oxygen during exhaustive exercise — from a recent race time without needing a lab treadmill or metabolic cart. VO2 max is the single best whole-system measure of aerobic fitness and is strongly predictive of all-cause mortality.
