Frequently Asked Questions
How are cycling climbs categorized (Cat 4, 3, 2, 1, HC)?
Climb categorization is based on length and grade: Climb Score = Length (m) × Average Grade (%) × 2. Scores over 8,000 are Cat 4, while scores over 80,000 are Hors Catégorie (HC).
What is VAM in cycling?
VAM (Velocità Ascensionale Media) measures vertical climbing speed in meters per hour. Elite professional climbers achieve 1500-1800 Vm/h on major alpine ascents.
