Climb Calculator

Calculate climb difficulty metrics: average gradient, VAM, and category ratings for mountain passes and climbs.

Coming soon.

This tool will help you analyze climbs by calculating:

  • Average gradient — Overall steepness of the climb
  • Maximum gradient — Steepest sustained section
  • VAM (Vertical ascent per hour) — Climbing speed metric
  • Category rating — Tour de France-style climb classification (Cat 4 to HC)

Enter distance, elevation gain, and time to get detailed climb analysis.
