Lukmanier Pass

Overview

The Lukmanier Pass sits in the Swiss Alps and enters the ride at an already-elevated start of 1,677 m, topping out at 1,973 m. That 296 m of net elevation gain across 6.2 km places it squarely in Category 3 territory — demanding enough to matter on a long day in the mountains, but well within reach for riders with solid aerobic fitness.

Total ascent logged on the climb is 403 m, which is noticeably higher than the net gain of 296 m. That gap signals the road isn't a clean unbroken ramp — expect at least one section where the gradient eases or dips before the road kicks back up.

How the Gradient Unfolds

The average gradient of 4.76% reads as moderate, and for much of the climb it genuinely is. This is a road where sustained tempo effort is possible, and riders comfortable at threshold pace can manage large sections without going into the red.

The caveat is the maximum gradient of 12.97%. That figure is nearly three times the average, which means there is at least one section — possibly more — where the road tilts sharply. A gradient spike of that magnitude on a climb that otherwise averages under 5% tends to catch riders off guard, particularly if they've been pushing hard on the easier lower slopes.

What to Expect, Roughly

• Lower and mid sections: Expect the more forgiving gradients to dominate here. The road allows a relatively consistent effort and invites riders to settle into a rhythm.
• Steeper pitches: One or more sections will approach or hit the near-13% maximum. These are short but sharp, and will feel significantly harder than the broader average suggests.
• Upper approach to summit: At 1,973 m, the air is thinner than at the valley floor, but the starting elevation of 1,677 m means altitude acclimatisation is less of a concern here than on higher Swiss cols.

Pacing Notes

The moderate average gradient tempts riders to go out hard. Resist that. The gap between the average (4.76%) and max (12.97%) gradients is wide enough that burning through matches early will make those steep pitches hurt considerably more.

Target a controlled effort through the first half, keeping power at or slightly below FTP. Use the flatter sections to recover, not to accelerate. When a steep pitch arrives, shift down early — waiting until you're already grinding is too late.

If you're uncertain what sustainable power looks like for a climb of this length and character, the FTP estimator is a useful reference before heading out.

Gearing

For most riders, a compact chainset (50/34) with a mid-range cassette (28 or 32-tooth) is comfortable for the majority of the climb. The 12.97% maximum gradient argues for having that 32-tooth available — or a 34 if your legs are already loaded from earlier in a long ride. Riders on standard gearing (53/39) should be confident in their threshold climbing ability before committing, as the steep sections will demand it.

The Bottom Line

The Lukmanier Pass is an accessible but honest Category 3 climb. The numbers don't lie: the average gradient is kind, but the maximum gradient is a genuine test. Ride it with respect for those sharp pitches, pace conservatively on the lower slopes, and keep a gear in reserve.
