VO2 Max Calculator

Measure your cardiovascular fitness level.

How to Use This Tool

  1. Enter your average running pace (min/km).
  2. Enter your resting heart rate.
  3. Get estimated VO2 max and fitness category.

The Formula

VO2 Max = 462.6 / (4.33 × Pace + 3.52). Higher VO2 max = better cardiovascular fitness.

Why It Matters

You run 5K in 25 minutes (8:03/mile pace) with resting heart rate of 62 bpm. Your estimated VO2 max is 44.2 — in the good category. Elite runners have 70-80. Training in zone 2 (60-70% max HR) is the fastest way to improve it.
