Calculate MAS after a field test
A field result, a speed reference. Find your estimate and explore what it means for your training paces.
What is it for?
Maximal aerobic speed (MAS) is a reference for pacing some sessions. Use a completed test to find an estimate in km/h and the corresponding track times.
How it works
- Choose the test you completed.
- Enter your six-minute distance or recorded VAMEVAL speed.
- Read the estimate and explore paces without changing your profile.
Your result
Half Cooper · 6 minutes
- Field-estimated MAS
- 16 km/h
- Pace at this speed
- 3:45 /km
| Distance | Time |
|---|---|
| 200 m | 0:45 |
| 400 m | 1:30 |
| 1,000 m | 3:45 |
The estimate depends on the protocol, measurement, pacing and conditions. It is neither measured VO₂max nor a predicted race time. The times shown are not a prescribed workout.
Only this preview value is transferred to the pace calculator. Your profile and plan stay unchanged.

Understand the calculation
Six-minute test: average speed over exactly 6 minutes is distance in metres ÷ 100, in km/h. It is used here as a MAS estimate. VAMEVAL: the tool retains the final speed validated by the supervisor, without converting a stage number. Times for 200, 400 and 1,000 m assume constant speed.
This tool reads a test already completed. Get support when organising a maximal effort; current discomfort or doubts about fitness to test call for professional advice.
Your questions, answered
Do I need an account to calculate?
No. Results and methods are freely available.

Does this calculation update my MAS in Koatch?
Saving keeps a private resource. To update your profile, use “Use this test in my profile”, enter the actual date, then confirm the preview. This adds the test and changes your MAS reference; existing workouts are not rewritten.
