Sulzenhals

Overview

Sulzenhals is a Category 2 climb in Austria, running 11.1 km from a start elevation of 979 m to a summit at 1622 m. Over that distance it delivers a net elevation gain of 643 m, which pins the average gradient at a moderate 5.78%. On paper that reads like a steady, mid-length effort well within the reach of most trained riders.

The paper figure is misleading. Total ascent for the climb is 926 m against a net gain of just 643 m, a 283 m gap. That extra elevation is climbing you do twice — ground you gain, give back on a descent or false flat, then have to reclaim. Undulation of this size means your legs pay for more vertical than the summit elevation suggests, and the recovery sections that create it are also chances to lose rhythm if you attack them wrong.

How the Gradient Unfolds

The 5.78% average is an accountant's number: it blends steep ramps with descents and flat spots into one tidy figure that describes no single section of the road. The presence of a 22.84% maximum against that average tells you the real climb is spiky, with short pitches far harsher than the mean.

• Flatter and recovery sections where the road eases or tips downhill — these are what create the 283 m of extra ascent.
• Repeated short climbs that stack up rather than one continuous drag, so effort comes in bursts.
• A steepest ramp touching 22.84% — a wall-like pitch that will spike your power well above anything the average implies.

Pacing Notes

On an undulating climb like this, chasing an even speed is a trap: holding pace up the 22.84% ramp forces a huge power surge, then the flatter sections let you coast and bank nothing. Pace to an even effort instead. Anchor your target to your sustainable power output and hold that ceiling on the steep pitches — accepting you'll slow down — rather than red-lining to keep the speedo steady. On the recovery sections, keep pedalling through to convert the descent into free rest without dropping off effort entirely. If you don't know your number yet, run the FTP estimator before you go.

Gearing

That 22.84% maximum governs your gear choice, not the 5.78% average. On a ramp this steep you want a compact or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 low gear gives you enough range to spin the wall without grinding to a stall. Check your setup before the ride: confirm the low sprocket you expect is actually fitted and that the rear derailleur handles it cleanly.

Summary

• Length: 11.1 km
• Average gradient: 5.78%
• Maximum gradient: 22.84%
• Net elevation gain: 643 m
• Total ascent: 926 m
• Category: 2

Sulzenhals rewards riders who read the profile rather than the average. Pace to effort, gear for the wall, and treat the 283 m of hidden re-climbing as part of the job.
