Sella di Barizze

Overview

Sella di Barizze is a genuine hors catégorie ascent, the kind of climb that earns its HC label through relentless, sustained difficulty rather than a single vicious ramp. Over 11.2 km the road lifts you from a start elevation of 551 m to a summit at 1612 m, a net gain of 1061 m. The total ascent registers at 1045 m, confirming that this is very nearly a pure uphill effort with almost no respite rolling back down along the way. With an average gradient of 9.44% and a maximum pitch of 14.33%, Barizze sits firmly among the hardest climbs a rider can take on, demanding both patience and reserves of strength.

How the Gradient Unfolds

The defining feature of Barizze is its steepness that simply does not let up. A 9.44% average sustained across 11.2 km is brutal — most climbs of this length average two or three points lower. Because the mean sits so high and the maximum is 14.33%, the difference between them is only 4.89 percentage points. That narrow spread tells you almost everything: there are no long flat recoveries hiding here. The steepest ramps at 14.33% bite hard, but even the "easier" stretches hover close to the average, so your legs never fully unload. Expect a wall that starts steep, stays steep, and finishes steep, with the gradient oscillating in a tight band all the way to 1612 m.

Pacing Notes

On a climb this uniform, discipline wins. Because there is nowhere to soft-pedal and recover, going into the red early is the classic Barizze mistake. Target an effort you can hold for the full 11.2 km — for most riders that means settling in just under threshold and refusing to chase the steep 14.33% ramps. Your FTP is the number that matters most here: a climb of this length at 9.44% will be ridden very close to that ceiling for the entire duration. If you are unsure where yours sits, run the numbers through the FTP estimator before you commit to a pace. Meter the 14.33% pitches by shifting early and holding cadence rather than lurching out of the saddle.

Gearing

Do not under-gear this one. With an average of 9.44% and ramps to 14.33% over 11.2 km, low ratios are not a luxury — they are what keeps your cadence and your back intact near the 1612 m summit. A compact 34-tooth chainring paired with a wide cassette is the sensible baseline. A 34×32 will get most fit riders up, but on a climb that gains 1061 m without relief, a 34×34 gives you the extra margin to spin the steepest ramps instead of grinding them. If your bike can take it, err toward the easier gear.

Summary

Sella di Barizze is a true HC climb: 11.2 km of unbroken steepness averaging 9.44%, spiking to 14.33%, hauling you 1061 m up to a 1612 m summit. Respect the pacing, bring low gears, and it rewards the disciplined rider.
