Summary
Enter elevation gain and time (or gradient and speed) to calculate VAM in m/h, then estimate w/kg from your climb.
How it works
- Choose your input method: elevation + time, or gradient + speed.
- Enter elevation gained in meters and your total climb time, or road gradient and speed.
- Click Calculate to see your VAM in meters per hour.
- Optionally enter your body weight to get an estimated watts per kilogram from the climb.
- Use the reference table to compare your VAM against known climbing benchmarks.
Use cases
- Benchmark your climbing fitness against pro and amateur cyclist standards.
- Track VAM improvement across repeated attempts on the same climb.
- Estimate power output when you have no power meter but know gradient and speed.
- Plan a target pace for an upcoming timed climb or sportive.
- Compare VAM across different climbs of varying gradient to normalize difficulty.
- Set training goals by targeting a specific VAM range for your category.
