Passo Pordoi: the climb, its Grand Tour history and records
Passo Pordoi: each side of the climb, every Grand Tour passage since 1996 and the records, each figure with the source it comes from.
The climb
Veneto, Italy
| Side | Start | Length | Elevation gain | Average | Max | Summit | Hairpins | Source |
|---|---|---|---|---|---|---|---|---|
| Arabba | Arabba | 9.2 km | 644 m | 7 % | 10.4 % | 2240 m | 33 | climbfinder.com |
| Canazei | Canazei | 12.1 km | 786 m | 6.5 % | 9.8 % | 2237 m | 25 | climbfinder.com |
Each side from one source, linked. A dash: the sources we opened disagree or give no figure, so we leave it out.

How long would it take you?
Your time up Passo Pordoi at a steady power, from a physics model.
Advanced: rolling resistance and drag
Estimate from a physics model (Martin et al. 1998), on the average gradient. Wind, surface, pacing and steep sections change the real time. More cycling tools
How this is calculated
P × 0.977 = ½ · ρ · CdA · v³ + v · m · g · (sin θ + Crr · cos θ), θ = arctan(average gradient), m = rider + bike, g = 9.81; solved for the speed v, time = length / v. Air density ρ: NASA GRC troposphere: T=15.04-0.00649*h; p=101.29*((T+273.1)/288.08)^5.256; rho=p/(0.2869*(T+273.1)); h = mean of start and summit altitude.
