Tips for This Segment
- •Pace yourself - this is nearly 20km of climbing
- •The gradient is consistent, so find a sustainable rhythm
- •Hydrate well before and during - this will take over an hour for most
- •Consider using a fan - you'll generate a lot of heat

Frequently Asked Questions
The calculator uses Zwift's physics model including gradient effects, rolling resistance (Crr = 0.004), and aerodynamic drag. Estimates are typically within 5-10% of actual times, though individual performance varies based on pacing and fatigue.
For short segments (under 5 minutes), you can typically sustain 110-120% of FTP. For medium efforts (5-20 minutes), aim for 100-105% of FTP. For long climbs like the Alpe, sustainable power is usually 85-95% of FTP.
Segment times are calculated for solo efforts without drafting. In a group, you may be slightly faster on flat sections, but climbing times are minimally affected by drafting since air resistance is less significant at climbing speeds.
Differences can occur due to: inconsistent pacing, fatigue from earlier riding, different in-game equipment, use of power-ups, or starting the segment with varying momentum.
Benchmarks are calculated using the segment's actual gradient profile at various W/kg levels. They represent steady-state efforts typical for trained cyclists at each fitness level.
