Ruppen Pass

Overview

Ruppen Pass is a Category 2 climb in Switzerland, running 10.9 km from a start elevation of 409 m to a summit at 1,009 m. On paper that is 600 m of net elevation gain at an average gradient of 5.51%, which reads as a steady, mid-length effort well inside the range most trained riders can hold at tempo.

The paper number is only part of the story. The total ascent over the climb is 801 m — 201 m more than the net gain of 600 m. That gap is undulation: the road gives back roughly 200 m of descent along the way, and you have to re-earn every metre. The practical effect is that your legs do more work than the net profile suggests, and any recovery you get on the flatter or downhill sections is money you pay back on the next ramp.

How the Gradient Unfolds

The 5.51% average hides the shape of the climb. Undulating profiles like this one rarely sit at their average for long — the flat and descending sections drag the number down, which means the pitches that actually climb are steeper than 5.51%. Expect the effort to come in bursts rather than as one continuous grind.

• Flatter and recovery sections where the gradient eases or tips downhill, letting you spin and eat
• Repeated short climbs stacked through the middle, each one resetting your legs
• The steepest ramp reaching 17.2% — a sharp pitch that will force you out of the saddle or into your easiest gear

Pacing Notes

On an undulating climb, even-effort beats even-speed. Chasing a constant speed means over-driving the steep ramps and coasting the flats, which spikes your fatigue for no time saved. Instead, hold a steady sustainable power output and let your speed rise and fall with the road — fast on the shallow sections, slower on the 17.2% pitches.

Cap your steep-section surges just above threshold and use the flatter parts to bring your average back down. If you do not know your numbers, run the FTP estimator first so you are pacing to real data, not guesswork.

Gearing

The 17.2% maximum gradient is what dictates your setup, not the 5.51% average. On a ramp that steep, an under-geared bike will grind you to a crawl. Run a compact (34-tooth inner) or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 low gear gives you the cadence to spin the steep pitches instead of mashing them. Check your chainset and cassette before the ride; the summit is not the place to discover you are one sprocket short.

Summary

• Length: 10.9 km
• Average gradient: 5.51%
• Maximum gradient: 17.2%
• Net elevation gain: 600 m
• Total ascent: 801 m
• Category: 2

Ruppen Pass is a Category 2 climb that rewards riders who read the profile rather than the average. Pace it on power, gear it for the 17.2% ramp, and treat the 201 m of hidden ascent as the real cost of the day.
