Lomsattel

Overview

Lomsattel is an HC climb in Italy, one of those categorised beyond the standard numbering because the sustained demand outstrips anything a Cat 1 label can carry. It runs 9.6 km from a valley floor at 556 m to a summit of 1,469 m, giving a net elevation gain of 913 m. At an average gradient of 9.47%, this is a relentless ascent with no token gradient to hide behind.

The important number here is the one that does not appear in the average. Net gain is 913 m, but total ascent is 1,349 m — a 436 m gap. That difference is undulation: descents and false flats you climb back through on the way up. You do not simply gain 913 m; you climb 1,349 m of vertical, and every metre you give back on a dip is a metre you pay for twice. Treat Lomsattel as a longer climb than its net figure suggests.

How the Gradient Unfolds

A 9.47% average on undulating terrain is misleading in both directions. The dips pull the mean down, which means the climbing sections sit well above 9.47% to compensate. Expect ramps that bite hard, punctuated by brief releases where the road eases or tips downward before rearing up again.

• Short recovery sections and false flats where the road relents — use them, they are the reason total ascent exceeds net gain.
• Repeated punchy climbs stacked back to back rather than one smooth wall.
• A steepest ramp reaching 34.93% — a genuine wall that will force you out of the saddle or off the bike if you arrive over-geared.

Pacing Notes

On a climb this lumpy, chasing even speed will destroy you. The steep ramps would demand enormous surges to hold a fixed pace, and you would arrive at the summit empty. Instead, pace by even effort: hold a steady sustainable power output through the ramps and let your speed fall, then recover — do not accelerate — through the flatter sections.

The 436 m of re-climbing means your average power should sit slightly below what you would target on a smooth climb of the same length, because the surges cost extra. If you do not know your ceiling, run the FTP estimator before you ride and set a wattage cap you refuse to exceed on the lower slopes.

Gearing

The 34.93% ramp governs your setup, not the average. On a pitch that steep, standard compact gearing will have you grinding at a cadence that shreds your legs. Fit a compact or sub-compact chainset and a wide-range cassette — a 34×32 at minimum, and 34×34 if your derailleur clears it. The goal is spinning survival, not muscling a big gear. Check your chainset and cassette the day before; discovering you are over-geared halfway up a 34% wall is not a mistake you recover from.

Summary

• Length: 9.6 km
• Average gradient: 9.47%
• Maximum gradient: 34.93%
• Net elevation gain: 913 m
• Total ascent: 1,349 m
• Category: HC

Lomsattel rewards riders who respect the gap between net gain and total ascent. Pace by effort, gear low, and let the numbers — not your ego — govern the lower slopes.
