Würzjoch

Overview

Würzjoch is a genuine hors catégorie test of endurance. Over 23.3 km the road lifts you from a valley floor at 539 m to a summit at 1991 m — a net gain of 1452 m at an average gradient of 6.24%. Those numbers describe a climb that is long before it is steep: the HC label here is earned through sustained effort rather than wall-like ramps. The total ascent of 1500 m confirms there is a little rolling relief along the way, but only a little. This is a climb you settle into for the better part of an hour and simply keep turning over.

How the Gradient Unfolds

The defining figure is the gap between the 6.24% average and the 12.1% maximum. On a climb this long, that spread tells you the road is uneven — stretches of steady, honest grade broken by short pitches that bite hard. Because the net gain (1452 m) sits below the total ascent (1500 m), you can expect brief flatter or descending sections that break the rhythm. Those false recoveries are a trap: they tempt you to surge, then hand back the elevation you thought you'd banked. The smart read is to treat the 6.24% as your baseline and absorb the double-digit ramps toward 12.1% without panic, knowing they are exceptions rather than the rule.

Pacing Notes

On a 23.3 km climb, pacing is everything. Aim to ride the sustained sections just below your threshold and reserve headroom for the 12.1% pitches. Anchoring your effort to your FTP is the most reliable way to avoid blowing up early — target a percentage of that number you can hold for the full climbing duration, not just the opening kilometres. If you don't have a current figure, run the numbers through the FTP estimator before you go, then hold that ceiling patiently. With 1452 m of net gain to swallow, riders who start conservatively almost always finish faster than those who attack the lower slopes.

Gearing

The combination of length and steep ramps makes gearing a real decision, not an afterthought. For most riders tackling an HC climb of 23.3 km, a compact chainring paired with a wide-range cassette is the sensible baseline. A 34×32 will get strong climbers over the 12.1% pitches, but on a climb this sustained many riders will be far happier with a 34×34, which lowers your cadence-preserving bailout gear for the steepest sections and the fatigued final kilometres near 1991 m. If your bike can take it, err toward the easier ratio — spinning up a long climb beats grinding it.

Summary

Würzjoch rewards patience and punishes ego. Meter it out, gear low, and let the 6.24% average do the work while you save your matches for the 12.1% ramps. Cross the top at 1991 m knowing you've conquered one of the longer HC efforts in the book.
