Winterlücke

Winterlücke cycling climb profile

Winterlücke is a category 1 climb in CH that asks for patience more than aggression. The headline number is 23.5 km at an average gradient of 4.98%, but that average only tells part of the story. With 1172 m of net elevation gain from 1070 m to 2242 m, this is a sustained high-mountain effort where the cost comes from duration, altitude gain, and the need to keep pressure on the pedals for a long time.

The total ascent is 1193 m, only slightly more than the net gain. That matters. It suggests the climb is overwhelmingly positive from bottom to summit rather than a sawtooth road with repeated descents. In riding terms, there is not much free recovery hidden in the profile. Even if the gradient eases in places, the climb still trends upward almost continuously, so pacing errors compound.

How the gradient feels

An average of 4.98% across 23.5 km usually reads as manageable on paper, but Winterlücke should not be treated like a rolling tempo climb. The maximum gradient reaches 10.6%, which means the road contains pitches steep enough to force a real change in torque and cadence. Those harder sections are the danger point because they invite short surges above sustainable power.

The smarter interpretation is that Winterlücke is a long aerobic climb with sharper ramps embedded inside it. The average gradient gives you permission to settle into rhythm, but the max gradient warns against choosing a gear or pacing strategy built only around the average.

Pacing and gearing

Start below target, especially if riding by /glossary/ftp. On a climb this long, the first mistake is treating the lower average gradient as a reason to ride at the top of your range from the base. If the legs feel good after the early portion, that is useful information. If they feel good after a long stretch of climbing and after the steeper ramps, that is when you can lift the effort.

Gearing should leave enough room for the 10.6% sections without forcing low-cadence grinding. The key is not just surviving the steepest ramps, but exiting them without carrying too much muscular fatigue into the remaining climb. A compact, efficient climbing setup is more valuable here than a big-gear approach, because the profile rewards steady power more than punch.

For pacing, think in layers:

• Ride the opening conservatively and ignore the temptation to chase speed.
• Use the moderate average gradient to hold rhythm, not to overreach.
• Treat the 10.6% pitches as controlled pressure, not attacks.
• Save the strongest effort for the upper part, where the accumulated 1172 m of gain becomes the real opponent.

Winterlücke is hard because it is honest. The road gains almost everything it promises, with little apparent help from downhill relief. Respect the duration, keep the steep sections under control, and the climb becomes a measured endurance test rather than a slow unraveling.
