Ghisallo

Overview

Ghisallo is a Category 2 climb in Italy, running 8.4 km from a start elevation of 207 m to a summit at 754 m. Over that distance you take on a net elevation gain of 547 m at an average gradient of 6.5%. It is a mid-length effort with enough sustained pitch to reward riders who arrive with a plan rather than improvising off the front.

The number that shapes everything here is the gap between net gain and total ascent. You climb 547 m of net elevation, but the total ascent on the profile is 723 m. That 176 m difference is undulation: the road drops and rises again on its way up, giving back roughly a third as much elevation as it nets. The practical consequence is that a "6.5% average" understates the climbing you actually do, because part of your work is spent regaining ground you already lost on the intervening descents.

How the Gradient Unfolds

The 6.5% average is an accounting figure, not a lived one. Because the profile undulates, some stretches sit well below average while others spike hard above it, and the steepest ramp is far sharper than the mean suggests. Treat the average as a budget, not a pace target.

• Flatter and recovery sections where the descents inside the climb briefly ease the load and let you reset
• Repeated short climbs stacked between those dips, each demanding a fresh surge rather than a steady rhythm
• The steepest ramp, notably above the average gradient, where you cannot coast momentum from below

Pacing Notes

On a smooth climb you can chase even speed. On Ghisallo, don't. The undulation means holding constant speed forces huge power spikes on every steep pitch and wasted watts on every dip. Instead, pace to even effort: hold a steady sustainable power output and let your speed rise and fall with the terrain. Accept slower speeds on the ramps and let the recovery sections do their job rather than hammering them.

If you don't know your sustainable ceiling, run the FTP estimator first. Anchoring your climb to a real number keeps you from redlining on the steepest ramp with kilometres still to go.

Gearing

Gearing is governed by the steepest pitch, not the average. Because the climb includes ramps well above 6.5%, come with margin: a compact (34-tooth) or sub-compact chainset paired with a wide-range cassette. A 34×32 covers most riders here, and 34×34 gives you a safety gear for the sharpest ramp when your legs are already loaded from the undulation. Check your setup before the ride. Confirming your smallest gear at the workbench is far cheaper than discovering it mid-ramp.

Summary

• Length: 8.4 km
• Average gradient: 6.5%
• Maximum gradient: 20.87%
• Net elevation gain: 547 m
• Total ascent: 723 m
• Category: 2

Ghisallo is a climb where the average lies and the undulation tells the truth. Pace to effort, gear for the steepest ramp, and treat the 176 m of extra ascent as the real cost of admission.
