Passo della Gavetta

Overview

Passo della Gavetta is a short, savage category 1 climb that packs an enormous amount of vertical into very little distance. Over just 6.4 km it drags you from a start elevation of 4 m near sea level all the way to a 709 m summit — a net gain of 705 m. That works out to an average gradient of 11.02%, a figure that would be punishing over half the distance, let alone the full length. There is no easing in and no long false-flat to recover on. From the moment the road tilts up, it stays up, and the 19.2% maximum gradient means the hardest ramps are genuinely leg-breaking.

How the Gradient Unfolds

The defining feature of Gavetta is its consistency of steepness. With a total ascent of 688 m spread across 6.4 km, the climb barely offers a break — the difference between the 705 m net gain and the 688 m of total ascent tells you there is almost no downhill relief along the way. Expect long stretches sitting well above the 11.02% average, punctuated by the sharpest pitches that touch 19.2%. On a climb this short, the average and the maximum sit close enough together that you rarely drop into anything that feels like rest. Plan for a wall that only occasionally softens, rather than a series of distinct steps.

Pacing Notes

On a climb averaging 11.02% for 6.4 km, pacing is really about power management above all else. Because the gradient rarely relents, you cannot coast to recover — every watt you overspend on the 19.2% ramps has to be repaid immediately. Anchor your effort to your FTP and aim to climb at or just below threshold, accepting short surges over the steepest sections only when the road forces you to. If you do not know your threshold number, run the numbers through the FTP estimator before you go, then hold back in the opening kilometres. The temptation from a 4 m start is to attack while the legs feel fresh, but with 705 m of climbing stacked ahead of you, restraint early pays dividends near the 709 m summit.

Gearing

Gearing is not optional insurance here — it is the difference between spinning and grinding to a halt. For a sustained 11.02% average spiking to 19.2%, most riders will want the widest ratios they can fit. A compact 34-tooth chainring paired with a 34×32 is the sensible baseline, giving you a manageable cadence on the bulk of the climb. But on the 19.2% ramps a 34×32 can still feel overgeared, so if your derailleur allows it, step up to a 34×34 for extra margin. The lighter you gear, the more you protect your legs for the summit rather than blowing up on the steepest pitch.

Summary

Passo della Gavetta is a proper leg-breaker: short in distance, enormous in intensity. With an 11.02% average, a 19.2% maximum and 705 m of net gain in only 6.4 km, it rewards conservative pacing and generous gearing. Respect the opening slopes, hold something back, and let the summit come to you.
