Barco dei Montoni

Overview

Barco dei Montoni is a hors catégorie climb, the hardest rating a road can carry, and its numbers explain why. Over 16.2 km the road lifts you from a valley floor at 199 m to a summit of 1351 m — a net gain of 1152 m, with 1151 m of total ascent packed into a single, near-relentless push. The average gradient sits at 7.11%, and the steepest pitch bites at 12.41%. This is a climb of endurance first and punch second: it asks for a sustained, high effort held for the better part of an hour rather than a series of short, savage walls.

How the Gradient Unfolds

A 7.11% average across 16.2 km is deceptively even on paper, but the 12.41% maximum tells you the road is not flat-lining at its mean. Expect the true grind to hover a little above and below the average for long stretches, punctuated by ramps that lean toward that 12.41% ceiling. The small gap between net gain (1152 m) and total ascent (1151 m) is telling: there is almost no descending or false flat to recover on. Once you start climbing, you keep climbing. Treat the steeper ramps as brief overdrafts against your rhythm, not as the new normal — the road nearly always eases back toward its 7.11% baseline.

Pacing Notes

The single biggest mistake on a climb like this is starting too hard. With over 1150 m to gain, your effort should be governed by your FTP rather than by feel in the opening kilometres. Aim to settle just below threshold and hold it, letting the steep pitches nudge you briefly over and the shallower sections pull you back under. On a sustained HC effort, most riders will want to sit in a tempo-to-threshold band and refuse to chase the 12.41% ramps out of the saddle for longer than necessary. If you are unsure of your number, run the FTP estimator before you go and build your pacing plan around a realistic power target, not an optimistic one.

Gearing

For a 16.2 km climb averaging 7.11% with pitches to 12.41%, gear low and thank yourself later. A compact 34-tooth inner chainring is the sensible foundation. Paired with a 34×32, most trained riders can hold a workable cadence on the average grade while still having something in reserve for the ramps. If you weigh more, ride at lower fitness, or simply want to protect your legs across a full hour of climbing, step up to a 34×34 — the extra sprocket keeps your cadence honest on the 12.41% sections and spares your knees over 1152 m of ascent. There is no prize for grinding; spin it.

Summary

Barco dei Montoni is a proper HC test: long, consistent, and unforgiving, with 16.2 km and 1152 m of vertical between you and the 1351 m summit. Pace it by power, gear it generously, and respect the fact that the road barely lets up from bottom to top.
