Lötschenlücke

Lötschenlücke cycling climb profile

Lötschenlücke is a proper Category 1 climbing effort: long enough to punish early enthusiasm, steep enough in places to expose poor gearing, and sustained enough that the average gradient matters more than any single ramp.

The climb runs for 13.8 km from 1019 m to 1932 m, gaining 913 m from start to summit. On paper, the 6.62% average gradient suggests a controlled endurance climb rather than a wall. The important qualifier is the 12.17% maximum gradient. That gap between the average and the steepest pitch tells you the road is not simply a metronomic drag at one intensity. There are harder ramps hidden inside the broader rhythm, and those are where pacing mistakes compound.

How the gradient rides

With only the headline profile available, the honest read is that Lötschenlücke should be treated as a sustained climb with intermittent steep sections, not as a climb where you can plan around clearly defined sectors. The average sits in the range where a well-paced rider can stay seated and keep pressure on the pedals, but the maximum gradient is close to double that average. That means the climb likely changes character at points, forcing short periods of higher torque even if the overall effort remains aerobic.

The key tactical point is simple: do not let the average gradient lull you into riding the lower slopes too hard. A 13.8 km climb at 6.62% already demands patience. Add ramps up to 12.17%, and the cost of going over threshold early becomes much higher because recovery on the climb is limited. If you arrive at the steepest pitches already carrying fatigue, they stop being short interruptions and become the point where cadence collapses.

Pacing approach

Ride the opening as if the climb is harder than the average suggests. Settle into a sustainable climbing intensity, ideally below the number you would use for a shorter ascent. If you pace by power, anchor the effort around your climbing target rather than chasing speed, because gradient changes will make speed a poor guide. If you pace by feel, aim for controlled breathing and a cadence you can hold without grinding.

Use the steepest ramps as controlled surges, not attacks. Let power rise briefly if needed, but avoid turning every 12.17% pitch into a maximal effort. The goal is to keep the climb intact: steady pressure on the moderate sections, enough gear range for the ramps, and no panic when the road kicks up.

Gearing notes

The maximum gradient makes compact or climbing-friendly gearing the smart choice. Even strong riders benefit from having a low gear available, not because the entire climb is brutally steep, but because the steep sections arrive inside a long effort. Spinning through those ramps preserves muscle tension and keeps the effort closer to your aerobic ceiling.

For riders using /glossary/ftp to set intensity, Lötschenlücke is the kind of climb where discipline matters more than aggression. The profile rewards staying slightly conservative early, managing the steep pitches, and saving enough to ride the final kilometres with form rather than survival mechanics.
