Passo del Paretaio

Overview

Passo del Paretaio is a Category 2 climb in Italy, running 13.5 km from a valley floor at 200 m to a summit at 865 m. On paper the numbers are moderate: a net elevation gain of 665 m over that distance. That profile suggests a steady, manageable ascent, and for long stretches it is.

The paper figures, though, understate the workload. Against 665 m of net gain, the climb records 1440 m of total ascent. That 775 m gap is undulation: false flats, dips, and short descents that force you to climb the same metres more than once. Every one of those descents scrubs momentum you then have to rebuild, so the effort in your legs will run well ahead of what the net gain implies. Treat this as a climb that punches above its category.

How the Gradient Unfolds

The 4.94% average is an accounting artefact. With 1440 m of total ascent packed into 13.5 km, the road is rarely at 4.94%; it is either steeper than that or actively descending. The average is the midpoint of extremes, not a description of the surface under your wheels.

• Flatter and recovery sections where the road eases or tips downhill, letting the average settle
• Repeated short climbs stacked back to back, each one re-gaining lost elevation
• A punishingly steep signature ramp that spikes far above the average and defines the hardest moments

Pacing Notes

On an even climb you can hold a single steady effort. Here, undulation makes even-speed pacing a trap: chasing constant speed over the dips means surging on every ramp and burning matches you cannot get back. Pace to a target sustainable power output instead, and let your speed rise and fall with the terrain. Ease slightly on the descents, hold your ceiling on the ramps, and refuse to over-cook the steep pitches. Know your number before you start by running the FTP estimator, then ride to it rather than to the clock.

Gearing

The steepest ramp is what dictates your setup, not the average. Anything short of a low bailout gear will leave you grinding at low cadence and haemorrhaging power exactly where the climb is hardest. Run a compact or sub-compact chainset paired with a wide-range cassette — 34×32 or 34×34 gives you a genuine spinning gear for the worst pitches. Check your chainring and cassette before you ride; discovering you are under-geared halfway up is a mistake you only make once.

Summary

• Length: 13.5 km
• Average gradient: 4.94%
• Net elevation gain: 665 m
• Total ascent: 1440 m
• Category: 2

Passo del Paretaio rewards riders who read the profile rather than the headline. Respect the undulation, gear for the steepest ramp, and pace to power — do that, and its 665 m of net gain will feel earned rather than survived.
