Bocchetta di Luera

Overview

The Bocchetta di Luera is the kind of climb that reorganizes your entire ride around it. In just 5.6 km it hauls you from a start elevation of 393 m up to a summit at 1225 m — a net gain of 832 m, with a total ascent of 768 m once the small dips along the way are counted. The average gradient reads 14.92%, a figure so steep that it stops being a road grade and becomes a wall you negotiate one pedal stroke at a time. Add a maximum pitch of 25.9% and its hors catégorie (HC) rating makes complete sense: this is the hardest tier the classification system offers, above categories 1, 2, 3, and 4.

How the Gradient Unfolds

Numbers like these leave no room to hide. Averaging 14.92% over 5.6 km means there is no genuine recovery — the climb simply oscillates between very steep and terrifyingly steep. When the ramp bites hardest it reaches 25.9%, more than ten points above an already merciless average, so even the "easier" stretches feel like relief only by comparison. Because the net gain (832 m) exceeds the total ascent (768 m), the profile is relentlessly upward with barely a false flat to break the rhythm. Expect the gradient to fight you the whole way from 393 m to 1225 m, with the sharpest kicks likely to arrive exactly when your legs are already screaming.

Pacing Notes

On a climb this steep, pacing is survival. Your FTP is the anchor number here: on 14.92% gradients you will frequently be forced above threshold simply to keep the wheels turning, so the goal is to spend as little time over it as the terrain allows. Ride the shallower sections a touch harder to bank momentum before each 25.9% ramp, then settle back the instant the pitch eases. If you do not know your threshold, run the numbers through the FTP estimator before you commit — over 832 m of climbing, going out too hard in the first kilometre can cost you the entire summit. Keep your cadence as high as the gradient permits and treat the whole 5.6 km as a single sustained effort rather than a series of sprints.

Gearing

Do not under-gear this one. A compact 34-tooth chainring paired with a wide cassette is the minimum sensible setup for a sustained 14.92% average. A 34×32 will get many strong riders to the top, but on the 25.9% ramps it leaves almost no margin. If your legs or your fitness are anything short of exceptional, fit a 34×34 instead — that extra sprocket buys precious cadence exactly where the road is steepest, and over 5.6 km of climbing your knees will thank you. Mountain-bike-range gearing is entirely defensible here; there are no style points for grinding.

Summary

The Bocchetta di Luera is a pure HC test: short at 5.6 km, but savagely steep at 14.92% average with a 25.9% maximum, climbing 832 m from valley to summit. Respect the numbers, gear low, and pace with discipline.
