Grosse Scheidegg

Overview

Grosse Scheidegg is a Hors Catégorie pass in Switzerland, and the numbers justify that rating immediately. Over 8.1 km, the road climbs 963 m net — with total ascent reaching 1,084 m, meaning there is no meaningful relief on the way up. The average gradient sits at 11.92%, which places it firmly in the category of climbs where pacing off feel alone will end your ride early.

How the Gradient Unfolds

The climb begins at 982 m elevation and terminates at the summit at 1,945 m. That 963 m of net gain compressed into 8.1 km produces a relentless character. At nearly 12% average, there is no flat section buffering the effort — the road is consistently steep throughout.

The maximum gradient of 23.46% confirms that at least one section tips into genuinely severe territory. Ramps at that pitch require either a seated grind in your lowest available gear or a controlled out-of-saddle effort. The gap between the average (11.92%) and the maximum (23.46%) indicates the climb is not uniformly pitched — expect the steepest ramps to arrive as concentrated walls rather than a gradual build. Treat any slightly easier stretch as active recovery, not an invitation to accelerate.

Pacing Notes

With an average gradient above 10%, this is a climb where FTP-based pacing is essential rather than optional. If you do not have a current FTP figure, use the FTP estimator before attempting a timed effort.

Key pacing principles for Grosse Scheidegg:

• Start conservatively. At 11.92% average over 8.1 km, going 5–10% too hard in the opening kilometre compounds quickly. The total ascent of 1,084 m — higher than the net gain — confirms the road does not let up.
• Identify the steep ramps early. The 23.46% maximum gradient sections are where most riders blow up. Reduce power slightly before hitting them rather than reacting once you're already in oxygen debt.
• Use seated climbing as the default. Extended out-of-saddle efforts on a climb averaging nearly 12% accelerate cardiac drift. Reserve standing for the steepest ramps only.
• Manage cadence actively. On gradients in the 15–23% range, cadence tends to drop sharply. Shift before you stall — spinning at 65–70 rpm through the worst pitches is preferable to grinding at 50.

Gearing

This is not a climb to attempt on a standard 34/28 compact if you are not a strong climber. Given the 23.46% maximum gradient and 11.92% sustained average, a 34/32 or a 1x drivetrain with a 34-tooth or larger cassette is strongly advisable. Riders who arrive under-geared will pay for it in muscular fatigue long before the summit.

If you are comparing gearing requirements against other HC climbs in the region, the profile here is comparable in sustained severity to other Swiss alpine passes with similar average gradients — the short length of 8.1 km does not make it easier; it simply concentrates the pain.

Bottom Line

Grosse Scheidegg is a short, brutal HC climb. At 8.1 km with a 963 m net gain and nearly 12% average gradient, it has no easy kilometres. The 23.46% maximum punishes riders who arrive with insufficient gearing or no pacing strategy. Treat it with the same respect you would give any full HC alpine pass — because the data says that is exactly what it is.
