VAM Calculator (Climbing Speed)
Vertical metres per hour from any climb — the climber's currency, with W/kg cross-estimate.
VAM lets you compare climbing days across different mountains — 1,000 m/h is strong amateur, 1,650+ is what Grand Tour leaders post on final climbs. The W/kg conversion (yes, *that* Dr Ferrari's formula) works because on steep grades almost all power fights gravity; it loosens below ~6% where aero re-enters.
