I'm a software developer and bike enthusiast from Germany with over 10 years of cycling experience. I created this VO2 max calculator to help cyclists find their vo2 max based on known power and weight inputs.

How the Cycling VO2 Max Calculator Works

This calculator estimates your VO2 max using a research-based formula that converts your maximal 5-minute power output into oxygen uptake capacity.

The Formula

VO2 Max = (5-Minute Power × 10.8) / Weight + 7

Inputs

  • 5-Minute Power: Your maximum average power output sustained over a 5-minute all-out effort (watts).
  • Weight: Your body weight in kilograms.

This method assumes a strong relationship between maximal 5-minute power and VO2 max for trained cyclists. It tends to be most accurate when the 5-minute power test is performed all-out in a fresh, rested state.

Limitations

  • This is a field estimate, not a laboratory measurement
  • Most accurate for trained cyclists; less reliable for beginners
  • Results are affected by pacing strategy and motivation during the 5-minute test
  • Does not directly factor in age, sex, or altitude
  • Assumes proper warm-up and fresh legs for the test effort

Frequently Asked Questions

What is a good VO2 max for cycling?

For male cyclists: 40-50 is recreational, 50-60 is enthusiast, 60-70 is competitive amateur, and 70+ is professional level. Female cyclists typically measure 10-15% lower at similar training levels. VO2 max is measured in mL/kg/min.

How do you calculate cycling VO2 max from power?

Cycling VO2 max is estimated using the formula: VO2 max = (5-Minute Power × 10.8) / Weight + 7. Enter your maximum 5-minute power output and body weight into our calculator to get your estimated VO2 max.

What is the difference between VO2 max and FTP?

VO2 max represents your aerobic ceiling (maximum oxygen uptake), while FTP represents sustainable power for about one hour. FTP typically falls between 70-85% of your VO2 max power. VO2 max sets your potential; FTP shows how much of that potential you can sustain.

Can cycling improve VO2 max?

Yes, cycling is excellent for improving VO2 max. High-intensity interval training (HIIT) at 90-100% of maximum heart rate is most effective. Most cyclists can improve VO2 max by 10-20% with structured training, though genetic factors set your ultimate ceiling.
