The climb
Gradient profile
Overview
Selletta Battisti is a hors catégorie climb, the hardest rating there is, and its numbers explain why. Over 20.5 km the road lifts you from a start elevation of 176 m to a summit at 1725 m — a net gain of 1549 m, with 1554 m of total ascent once the handful of flatter dips are added back in. The average gradient sits at a punishing 7.54%, and the steepest pitch bites at 16.38%. This is a full-hour effort for most riders, a climb that rewards patience far more than aggression, and one where the difference between a good day and a shattered one is decided in the first third.
How the Gradient Unfolds
The gap between the 7.54% average and the 16.38% maximum tells the real story. A climb this long almost never holds a single steady grade; instead it breathes, stacking stretches well above average against short reprieves that pull the mean down. Because total ascent (1554 m) barely exceeds net gain (1549 m), there is very little false descent along the way — you are climbing almost continuously for the entire 20.5 km. That matters: there are no long recovery valleys to reset your legs. When the road tips toward that 16.38% wall, you absorb it and keep turning, because relief is measured in metres, not kilometres.
Pacing Notes
On a climb of this length, discipline is everything. Anchor your effort to your FTP and resist the temptation to chase the early ramps. Sustaining a full hour near threshold is realistic for trained riders, but 20.5 km leaves no room to bury yourself in the opening kilometres and hope to recover — you won't. Aim to ride the average grade steadily and save a little for the steep pitches, letting your effort spike briefly to 16.38% terrain rather than red-lining the whole way. If you're unsure what number to target, run yours through the FTP estimator first, then hold that ceiling with quiet discipline from base to summit.
Gearing
Do not under-gear this one. With 20.5 km at 7.54% average and ramps to 16.38%, a compact chainring paired with a wide-range cassette is the sensible baseline. A 34×32 gets most fit riders up the sustained sections without cadence collapse, but the 16.38% pitches — arriving deep into a 1549 m ascent when your legs are already loaded — argue strongly for a 34×34. That extra sprocket buys you a lower floor and lets you spin rather than grind, protecting your knees and your remaining matches. If your bike accepts it, size up. On an HC climb this long, easier gearing is never a weakness; it's insurance.
Summary
Selletta Battisti is a genuine hors catégorie test: long, relentless, and steep enough in places to break a poorly paced rider. Respect the distance, gear low, and meter your effort against threshold, and those 1549 metres of net elevation become a triumph rather than a survival story.
