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

  1. Choose your input method: elevation + time, or gradient + speed.
  2. Enter elevation gained in meters and your total climb time, or road gradient and speed.
  3. Click Calculate to see your VAM in meters per hour.
  4. Optionally enter your body weight to get an estimated watts per kilogram from the climb.
  5. 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.
