Bocchetta di Sette Sorelle

Overview

The Bocchetta di Sette Sorelle is a 14 km category 2 climb that rewards patience over raw power. It launches from 256 m and tops out at 812 m, a net gain of 556 m across a road that averages a friendly 3.97%. On paper that gradient reads almost gentle, and for long stretches it is — this is a climb you can settle into and ride at a rhythm rather than one that forces you into repeated surges. But the numbers hide a twist: a maximum pitch of 11.92% waits somewhere along the way to remind you that "steady" and "easy" are not the same thing.

With 565 m of total ascent against 556 m of net gain, the road barely gives anything back. There are essentially no descents to recover on — just a persistent, honest drag upward for the better part of an hour for most riders.

How the Gradient Unfolds

The story here is the gap between the 3.97% average and the 11.92% maximum. A climb that averaged near four percent evenly would feel almost conversational. Instead, that near-12% spike tells you the gradient is uneven: mellow ramps that let your heart rate settle, punctuated by at least one bite roughly three times steeper than the mean.

Do the math on the whole and it comes together cleanly. Fourteen kilometres, 556 m of net elevation gain, and the road climbing almost every metre of the way (565 m of total ascent means only about 9 m of dip across the entire route). Expect to spend most of your effort in the 3–5% band, then brace for the single hard kick that defines the climb's character.

Pacing Notes

Because the average is modest, the temptation is to attack from the bottom. Resist it. The right approach is to hold a sustainable effort at or just below your threshold on the shallow sections, banking energy for the 11.92% ramp where you'll inevitably spike well above FTP for a minute or two.

If you don't already know your threshold power, plug in a recent effort using the FTP estimator before you ride. Knowing that number turns this climb from a guessing game into a paced effort: sit at a comfortable steady wattage across the 3–5% stretches, then accept a short, controlled overshoot on the steep pitch rather than blowing up trying to hold your average speed.

Gearing

For a 14 km climb averaging 3.97%, most riders will be perfectly happy on a compact chainring paired with a wide-range cassette. A 34×32 bottom gear is a sensible baseline and will carry you comfortably through the majority of the ascent at a spinning cadence.

That said, the 11.92% maximum is the deciding factor. If you tire on longer efforts or simply prefer to protect your knees, drop to a 34×34. The extra rear cog costs you almost nothing on the flatter ramps but gives you a genuine lifeline on the steep kick, letting you stay seated and turning the pedals instead of grinding to a near-halt.

Summary

The Bocchetta di Sette Sorelle is a climb of steady rhythm with one sharp exclamation point. Pace the shallow gradient conservatively, gear low enough to absorb the near-12% ramp, and it becomes a satisfying, honest ascent to 812 m.
