Hirschbergsattel

Overview

Hirschbergsattel is a hors catégorie (HC) climb in Austria, running 9.9 km from a start elevation of 717 m to a summit at 1,633 m. Over that distance it delivers a net elevation gain of 916 m, which is enough to place it firmly in the hardest category of paved and gravel ascents. This is a full-length effort: at nearly 10 km with an average gradient of 9.28%, there is no easy stretch that lets you switch off.

The number that reshapes the day is total ascent. The road climbs 1,125 m in total while gaining only 916 m net — a difference of 209 m. That gap means the climb undulates: you give back roughly 209 m of descent along the way and have to re-earn it. For your legs, this reads harder than the net figure suggests. Every metre lost to a dip is a metre you climb twice, and those recoveries rarely come where you want them.

How the Gradient Unfolds

The 9.28% average is a blend, not a constant. Because 209 m of the ascent is spent recovering lost ground, some sections sit well below average while others spike far above it to compensate. The steepest ramp reaches 25.71% — a wall that will force you out of the saddle or into your lowest gear regardless of how you were pacing.

Across the profile, expect:

• Flatter or gently descending recovery sections where you regain rhythm and eat
• Repeated short climbs stacked back-to-back after each dip
• A single steepest ramp near 25.71% that demands everything is in reserve

Pacing Notes

On a steady climb you can hold even effort and let speed vary. Hirschbergsattel's undulation punishes that instinct. If you chase even speed on the descents and flats, you will spike your power on every re-climb and detonate before the summit.

Anchor your ride to sustainable power output instead. Hold a controlled percentage of that ceiling on the sustained pitches, soft-pedal or freewheel the descents, and accept that your speed will swing wildly. Before you go, set your target with the FTP estimator so your numbers on the road are real, not guessed.

Gearing

The 25.71% maximum gradient governs your setup, not the 9.28% average. On a ramp that steep, standard road gearing will grind you to a stall. Fit a compact or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you a fighting spin against the wall. Check the setup on your actual bike before the ride; discovering you are over-geared on a 25% pitch is not a mid-climb fix.

Summary

• Length: 9.9 km
• Average gradient: 9.28%
• Maximum gradient: 25.71%
• Net elevation gain: 916 m
• Total ascent: 1,125 m
• Category: HC

Treat Hirschbergsattel as a full HC effort with a sting in the profile. The 209 m gap between net gain and total ascent is the detail that separates riders who pace it well from those who fade — respect the undulation, gear low, and hold your power.
