Cycling VO2 Max Calculator

Estimate your cycling VO2 Max based on your power output and physiological data. VO2 Max is the maximum amount of oxygen your body can utilize during intense exercise and is a key indicator of cardiovascular fitness.

Age Your age in years

Gender

Weight Your weight in kilograms

Resting Heart Rate Your resting heart rate in beats per minute (measure in the morning)

Test Duration Duration of your cycling test in minutes

Average Power Output Average power output during your test in watts

Maximum Heart Rate Your maximum heart rate in bpm (leave blank to estimate)

Quick Examples:

How to Use This Calculator

Enter your personal information (age, gender, weight)
Measure your resting heart rate in the morning before any activity
Complete a cycling test at maximum effort for 5-60 minutes
Record your average power output during the test
Optionally enter your maximum heart rate if you know it
Click Calculate to see your estimated VO2 Max and fitness level

Formula Used

VO2 Max = (Power Output × 12) / Weight + (HRmax - HRrest) × 0.05

Where:

Power Output = Average power in watts during the test
Weight = Body weight in kilograms
HRmax = Maximum heart rate (estimated as 220 - age if not provided)
HRrest = Resting heart rate in beats per minute

Example Calculation

Real-World Scenario:

A 35-year-old male cyclist weighing 75kg wants to estimate his VO2 Max. He has a resting heart rate of 55 bpm and completed a 20-minute cycling test with an average power output of 250 watts.

Given:

Age = 35 years
Weight = 75 kg
Resting HR = 55 bpm
Power Output = 250 watts

Calculation:

Estimated HRmax = 220 - 35 = 185 bpm

VO2 Max = (250 × 12) / 75 + (185 - 55) × 0.05

VO2 Max = 40 + 6.5 = 46.5 mL·kg-1·min-1

Result: The cyclist's estimated VO2 Max is 46.5 mL·kg-1·min-1, which is classified as "Good" for his age and gender.

Common Mistakes & Tips

Using a poorly calibrated power meter or estimating power based on speed can lead to inaccurate VO2 Max calculations. Always use a properly calibrated power meter and ensure it's set up correctly for your bike.

Testing under different conditions (temperature, humidity, fatigue level, time of day) can significantly affect your results. Try to standardize your testing conditions for consistent measurements over time.

The test requires maximum effort to accurately estimate your VO2 Max. Pacing yourself or not pushing to your true limit will result in an underestimation of your actual VO2 Max.

Frequently Asked Questions

For most recreational cyclists, testing every 3-4 months is sufficient to track progress. Competitive athletes may test more frequently during different training phases. Avoid testing too often as the tests require maximum effort and adequate recovery time.

While this calculator provides a good estimate of your VO2 Max, laboratory testing with gas exchange analysis is more accurate. Field tests like this one typically have a margin of error of ±5-10%. However, they are much more accessible and still valuable for tracking changes over time.

VO2 Max values vary significantly based on age, gender, and training level. For recreational male cyclists, values typically range from 40-55 mL·kg-1·min-1, while elite male cyclists often exceed 70 mL·kg-1·min-1. Female recreational cyclists typically range from 35-50 mL·kg-1·min-1, with elite female cyclists often exceeding 60 mL·kg-1·min-1.
