Monte Zoncolan: the climb, its race history and records
Monte Zoncolan: each side of the climb, its passages in the big races since 1996 and the records, each figure with the source it comes from.
The climb
Friuli-Venezia Giulia, Italy
| Side | Start | Length | Elevation gain | Average | Max | Summit | Hairpins | Source |
|---|---|---|---|---|---|---|---|---|
| Ovaro | Ovaro | 9.8 km | 1206 m | 12.3 % | 23.3 % | 1730 m | 22 | climbfinder.com |
| Sutrio | Sutrio | 13.2 km | 1183 m | 9 % | 21.1 % | 1731 m | 15 | 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 Monte Zoncolan 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.
