Heubützli Pass

Overview

Heubützli Pass is a Category 1 climb in Switzerland, and it is a long one: 31.6 km from base to summit. It starts at 485 m and tops out at 1,922 m, for a net elevation gain of 1,437 m. On paper that reads as a steady, moderate ascent — the kind of climb you settle into for well over an hour and grind out at tempo.

The paper number is misleading. The net gain is 1,437 m, but the total ascent is 2,829 m — nearly 1,400 m more climbing than the elevation difference between start and summit suggests. That gap means the road repeatedly kicks up and drops back down, so you climb roughly 1,392 m of ground you then give away. Expect an effort closer to a much bigger day than the net figure implies, and plan your energy for the full 2,829 m, not the 1,437 m.

How the Gradient Unfolds

The 4.55% average hides a lot. With this much undulation, long stretches sit well below average — even flat or downhill — which means the climbing sections must run steeper than 4.55% to compensate. Do not trust the average to set your pace.

• Flatter and downhill recovery sections where you can eat, drink, and reset
• Repeated short climbs that stack up into the 2,829 m total ascent
• A steepest ramp far above the average — brace for it and pick the right gear early

Pacing Notes

On a climb this lumpy, chasing an even speed is a trap: holding the same pace over the steep ramps will spike you far above threshold and cost you on the back half. Ride to an even effort instead. Anchor to your sustainable power output and let your speed rise and fall with the road — spin the flatter and downhill sections to recover rather than hammering to keep the numbers up.

If you are unsure of the wattage you can hold across a 31.6 km effort, run the FTP estimator first and set a target that leaves headroom. With 2,829 m of total ascent, going out too hard is the single fastest way to unravel before the 1,922 m summit.

Gearing

The steep ramps on Heubützli Pass are what govern your gearing, not the gentle average. Run a compact or sub-compact chainset with a wide-range cassette — a 34×32 or 34×34 gives you a bailout for the sharpest pitches while keeping cadence up over the repeated short climbs. On a 31.6 km climb with this much cumulative ascent, spinning a low gear preserves your legs far better than muscling a big one. Check your actual setup before the ride; the summit is a long way to discover you are over-geared.

Summary

• Length: 31.6 km
• Average gradient: 4.55%
• Net elevation gain: 1,437 m
• Total ascent: 2,829 m
• Category: 1

Heubützli Pass is a climb that punishes riders who read only the headline numbers. The 4.55% average and 1,437 m net gain look manageable, but the 2,829 m of total ascent over 31.6 km is the figure that decides your day. Pace to effort, gear low, and respect the undulation.
