Passo di Lucendro

Overview

Passo di Lucendro is an HC climb in Switzerland, and its category is earned honestly. Over 7.1 km it delivers a net elevation gain of 841 m, starting at 1,508 m and topping out at 2,349 m. An average gradient of 11.87% across that distance puts it in the top tier of paved climbs — there is no long false-flat approach here, just sustained steep road from bottom to top.

The number that reshapes the effort is total ascent: 1,127 m against a net gain of 841 m. That 286 m gap means the road undulates — it kicks up, drops back, and climbs again, so you pay for more vertical than the point-to-point figure suggests. On a climb this steep, those extra meters land on already-loaded legs, and the descents are too short to recover on. Treat the 11.87% as a floor for your effort, not a ceiling.

How the Gradient Unfolds

An 11.87% average hides a road that refuses to settle. Because 286 m of the total ascent comes from repeated pitches rather than one clean grade, the gradient swings hard around the mean — stretches well into the mid-teens sit next to brief levelling-off that arrives too late to matter. The steepest ramp bites at 34.22%, a wall that demands you already be in your easiest gear before it hits.

• Short recovery dips where the road briefly eases — do not squander them by surging
• Repeated steep pitches stacked back-to-back, the signature of this profile
• The steepest ramp near 34.22%, where cadence collapses if you are over-geared

Pacing Notes

On a smooth climb, even-effort and even-speed pacing nearly converge. Here they diverge sharply. Chasing an even speed means overcooking the steep ramps and blowing up; instead, hold a steady sustainable power output and let your speed fluctuate — slow on the walls, quicker through the dips. Because the undulation adds 286 m of extra climbing, budget for a longer, harder effort than 841 m of net gain implies. Know your ceiling before you start: run the numbers through the FTP estimator and cap yourself a notch below it on the lower slopes.

Gearing

The 34.22% ramp governs your setup entirely. A standard compact alone will not save you — pair a compact or sub-compact chainset with a wide-range cassette. A 34×32 is the minimum; 34×34 or wider gives you the low gear to keep turning the pedals on the steepest wall instead of grinding to a stall. Check your chainset and cassette the day before, not at the trailhead — swapping a cassette at 1,508 m is not a plan.

Summary

• Length: 7.1 km
• Average gradient: 11.87%
• Maximum gradient: 34.22%
• Net elevation gain: 841 m
• Total ascent: 1,127 m
• Category: HC

Passo di Lucendro rewards riders who respect the gap between net gain and total ascent. Gear low, pace to power, and let the road's undulation come to you rather than fighting it.
