Bocchetta di Pisone cycling climb profile
Bocchetta di Pisone is not a climb to ride on feel alone. At 23.5 km with an average gradient of 8.66 percent, it sits firmly in the category of long, sustained climbing where pacing discipline matters more than early confidence. The start is at 435 m and the summit is at 2473 m, which means the road gains 2038 m from bottom to top. That is the defining feature of the climb: the effort is not just steep, it is prolonged.
The HC classification makes sense from the numbers. An 8.66 percent average over this distance leaves very little room for easy recovery, because any flatter ground would need to be balanced by steeper sections elsewhere. The listed maximum gradient of 36.65 percent is the major warning sign. Without segment-by-segment data, it is not possible to say where that ramp appears, but it tells you the climb is not a simple metronomic alpine drag. There is at least one extreme pitch that can distort the effort if you arrive over-geared or already riding above threshold.
How the gradient unfolds
From the base to the summit, the climb should be approached as a long threshold-management problem. The average gradient is already hard enough to demand a compact effort, and the maximum gradient suggests the profile includes violent changes rather than a smooth, predictable rise.
That combination changes the way the climb rides. On a steadier climb, you can often settle just below /glossary/ftp and let the rhythm carry you. On Bocchetta di Pisone, the safer assumption is that rhythm will be interrupted. The steepest ramps will force torque spikes, and those spikes matter because they come inside a 23.5 km climb, not a short hill where you can afford to burn a match and recover later.
Pacing and gearing notes
Start conservatively. The opening effort should feel almost too controlled, because the climb has enough vertical gain to punish anyone who rides the first section like a standalone ascent. The target is not to avoid suffering, but to delay the point where cadence drops and every steep pitch becomes a low-cadence grind.
Gearing should be chosen for the maximum gradient, not the average. An 8.66 percent average already calls for climbing gears, but a stated maximum of 36.65 percent means riders should prioritize a bailout gear over small efficiency gains on the steadier sections. If your easiest gear only works when you are fresh, it is not low enough for this climb.
Practical approach:
- Ride the lower slopes below the effort you think you can hold to the summit.
- Keep cadence protected whenever the road allows it, because torque will spike on the steepest ramps.
- Avoid chasing speed changes. On a climb this long, power control matters more than momentary pace.
- Fuel early, because a 2038 m net gain leaves little margin for catching up once the gradient bites.
The best ride here is measured, not dramatic: control the first half, survive the steepest pitches without flooding the legs, then use whatever is left as the summit finally comes into reach.
