Passo del Brattello cycling climb profile
Passo del Brattello is a long Italian category 2 climb: 20 km from bottom to summit, rising from 187 m to 1033 m. On paper, the 4.22% average gradient makes it look controlled rather than brutal, but that headline number is only part of the story. The maximum gradient reaches 11.93%, which means this is not a uniform drag. The climb has enough easier road to pull the average down, but enough steepness to punish anyone who rides it like a steady tempo climb from the first pedal stroke.
That contrast is the main tactical feature of the Passo del Brattello cycling climb. A 20 km ascent at this average can feel deceptively manageable early because the required power is not extreme if you stay disciplined. The problem is that nearly 12% ramps change the cost of the ride quickly. If you arrive at those sections already above target, the climb stops being aerobic and starts becoming a series of recoveries from efforts you did not need to make.
How the gradient unfolds
With 846 m of net elevation gain across 20 km, the climb rewards patience more than aggression. The average tells you the road is broadly climbable in rhythm, while the maximum gradient tells you that rhythm will be interrupted.
The most useful way to think about the ascent is as a long endurance climb with short moments that demand torque. The easier portions are where you should keep the pressure smooth and resist the temptation to chase speed. The steeper ramps are where gearing and cadence matter more than pride. If you let cadence collapse on the 11.93% sections, the effort becomes muscular fast, and that cost accumulates over the remaining distance.
Pacing notes
Ride the first part as if the climb is harder than the average suggests. For most riders, that means sitting below threshold rather than trying to make the numbers look good early. Use perceived effort alongside power because the changing gradient can make speed misleading.
A sensible pacing frame:
- Start controlled and keep breathing stable.
- Treat the steepest ramps as short lifts, not attacks.
- Back off slightly after each hard section to keep the climb aerobic.
- Save any sustained push for the final portion, once the length is no longer the main risk.
If you pace by FTP, this is the type of climb where small spikes matter. A few unnecessary surges on a 20 km ascent can turn a manageable category 2 effort into a slow grind.
Gearing and ride feel
Because the climb averages 4.22% but touches 11.93%, gearing should be chosen for the steepest gradients, not the average. A setup that feels perfect on the main body of the climb may leave you over-geared when the road pitches up.
Aim for a gear that lets you stay seated through the harder ramps without dropping into a low-cadence grind. The climb is long enough that repeated torque-heavy efforts will take more out of you than a slightly easier gear and steadier cadence. That is the practical lesson of Passo del Brattello: the average gradient invites confidence, but the length and sharper ramps reward restraint.
