Forcella Valsorda

Overview

Forcella Valsorda is a genuine hors catégorie test. Over 21 km it climbs from 378 m to a summit of 2257 m, a net elevation gain of 1879 m at an average gradient of 8.95%. The category tells you everything you need to brace for: HC is the hardest rating there is, sitting above categories 1, 2, 3, and 4. This is not a climb you ride into casually. Total ascent across the road comes to 1842 m, meaning the ascent is almost relentlessly upward with only the faintest breaks to recover.

How the Gradient Unfolds

An 8.95% average over 21 km is punishing on its own, but the number that reshapes your ride is the 22.31% maximum. That is more than double the average, so the climb is not a steady wall — it stacks steeper ramps on top of an already demanding baseline. When a climb gains 1879 m net but logs 1842 m of total ascent, nearly every metre of the road tilts upward; there is little rolling relief to hide in. Expect long stretches sitting close to or above the 8.95% mean, punctuated by pitches that surge toward that 22.31% figure. Those spikes are where the climb is won or lost, and where riders who went out too hard on the lower slopes pay the price.

Pacing Notes

On a climb this long and steep, discipline beats bravado. Anchor your effort to your FTP and hold something in reserve for the ramps toward 22.31%. If you do not know your current threshold, run the numbers first with the FTP estimator so you can pick a sustainable target rather than guessing. A useful mental model: settle into a rhythm you could hold for the full 21 km at the 8.95% average, then accept short surges above threshold on the steepest pitches and recover the moment the road eases. Gaining 1879 m in a single effort demands patience — the summit at 2257 m rewards riders who ration their matches from the very bottom at 378 m.

Gearing

Gear for the 22.31% spikes, not the 8.95% average, and you will thank yourself. For most riders a compact 34-tooth chainring paired with a wide cassette is the sensible floor here. A 34×32 will get many strong climbers up the sustained sections, but on a 21 km climb with ramps toward 22.31% the extra range of a 34×34 buys you a lower, more spinnable gear that protects your knees and your legs over 1879 m of gain. If your setup allows an even easier ratio, this is exactly the climb that justifies it. The goal is to keep cadence up rather than grinding to a standstill on the steepest pitches.

Summary

Forcella Valsorda earns its HC label without argument: 21 km, an 8.95% average, ramps to 22.31%, and 1879 m of net gain to a 2257 m summit. Pace it off your threshold, gear for the steep ramps, and let the numbers, not your ego, dictate the day.
