Passo del Paretaio cycling climb profile
Passo del Paretaio is a short, concentrated climbing effort in Italy. On paper it is 2.4 km long at an average gradient of 7.76%, rising from 80 m to 267 m. That makes it less a long mountain test and more a sustained power climb: hard enough that the gradient matters immediately, short enough that pacing errors are expensive because there is not much road left to recover.
The key number is the relationship between the average and the maximum gradient. With a maximum of 9.63%, the climb does not appear to be defined by savage double-digit ramps. Instead, the profile points to a steady high-single-digit effort, where the difficulty comes from limited relief rather than one isolated wall.
How the gradient unfolds
From the bottom, the climb gains height quickly. The start elevation is 80 m and the summit is 267 m, with 187 m between the two points. Across only 2.4 km, that rise produces a sustained climbing feel from the first part of the ascent.
Because the average sits at 7.76% and the maximum is 9.63%, the practical read is that the road likely spends much of its time close to the average, with short steeper sections rather than a wildly uneven profile. That matters tactically. On a climb like this, surging early into the steeper touches can push you over your sustainable power before the climb has really opened up.
It is listed as category 3, which fits the character: not a major pass by duration, but definitely enough climbing density to split a group, expose weak legs, or force a rider above comfort if the pace is lifted at the base.
Pacing and gearing notes
Treat Passo del Paretaio as a controlled threshold-style effort, not a sprint from the bottom. The climb is short, but 2.4 km at 7.76% is long enough that an over-eager opening can turn the upper half into damage control.
Practical approach:
- Start just below the effort you think you can hold to the summit.
- Stay seated where possible and avoid grinding the steeper touches.
- Shift before the gradient bites, not after you are already losing momentum.
- If riding in a group, expect the decisive pressure to come from sustained tempo rather than one violent acceleration.
For riders pacing by power, this is the kind of climb where knowing your /glossary/ftp is useful, because the best ride will come from resisting the urge to chase every early acceleration. The summit comes quickly, but not quickly enough to ignore discipline.
