Horbüelpass

Overview

Horbüelpass is a category 1 climb that asks for genuine respect. Over 14.9 km it averages 6.15%, lifting you from a valley floor at 658 m to a summit at 1576 m. That is 918 m of net elevation gain, with 899 m of total ascent logged along the way — the two figures sitting within 19 m of each other, which tells you this is an almost relentlessly upward road with very little false flat or recovery descent to break the rhythm.

The average of 6.15% is the kind of gradient that never feels catastrophic in any single moment, yet never lets you settle either. Add a maximum pitch of 15.78% and you have a climb defined less by one brutal wall than by sustained, honest difficulty. It is a long effort, and long is the operative word.

How the Gradient Unfolds

Think of Horbüelpass as three-quarters of an hour spent at or near threshold rather than a series of discrete features. The 6.15% average is your baseline, but the road clearly does not hold that number the whole way — the 15.78% maximum sits well above it, so expect ramps that spike hard before easing back toward the mean.

Because total ascent (899 m) is so close to net gain (918 m), the climb almost never gives elevation back. There is no meaningful downhill to soft-pedal and refuel. Every metre you climb toward 1576 m is a metre that stays climbed. Plan your effort around that: the steep sections are surges above a consistently taxing floor, not spikes interrupting easy ground.

Pacing Notes

On a climb this long, discipline beats ego. Ride the first third comfortably under threshold. The average of 6.15% is close enough to most riders' sustainable ceiling that going into the red early will cost you dearly across 14.9 km.

Anchor your pacing to your FTP. Riding the bulk of Horbüelpass a touch below that number leaves headroom for the 15.78% ramps, where power naturally jumps as cadence falls. If you don't know your threshold, use the FTP estimator to set realistic targets before you start.

Meter the steep pitches: let power rise briefly over the wall, then settle straight back to your steady effort. With 918 m to gain and almost no descent to recover on, a smooth, even output will beat a stop-start attack every time.

Gearing

For a 14.9 km climb averaging 6.15% with pitches to 15.78%, gear generously. A compact 34-tooth chainring paired with a 34×32 low is a sensible starting point for strong climbers, keeping cadence up on the steady grade.

For most riders — or anyone tackling this fatigued or loaded — go one step easier and fit a 34×34. On the 15.78% ramps that extra range is the difference between spinning and grinding to a near-standstill, and over a summit at 1576 m your legs will thank you for the softer bailout gear.

Summary

Horbüelpass is a long, honest category 1 test: 14.9 km of near-continuous climbing at 6.15%, with steep 15.78% surges and 918 m of net gain to a 1576 m summit. Pace it to your threshold, gear it low, and let its consistency work for you rather than against you.
