VO2max = (−4.6 + 0.182258v + 0.000104v²) ÷ %VO2max(t)

(Daniels–Gilbert, 1979 — v in m/min, t in minutes; equivalents use Riegel ^1.06)

Enter a recent race time above to estimate your VO2 max and see equivalent times at every distance. Or start from an example:

This estimates running economy-adjusted VO2 max (VDOT) from a race result — it assumes an even-paced, all-out effort in good conditions. A lab-measured VO2 max can differ; the classification bands are general population norms, not running-specific.
