Hirschbichl

Overview

Hirschbichl is a Category 1 climb in Austria, stretching 5.9 km from a start elevation of 663 m to a summit of 1,183 m. On paper it delivers a net elevation gain of 520 m at an average gradient of 8.84% — already a serious sustained effort that puts it firmly in the harder tier of categorized climbs. The numbers alone tell you this is not a climb you drift up; it demands respect from the first pedal stroke.

But the net figure understates the work. The total ascent is 757 m — 237 m more than the net gain of 520 m. That gap means the road undulates: you climb, give some back on brief descents or flatter shelves, then climb again. Every metre lost to a dip has to be re-earned, so the true vertical workload is roughly 45% larger than the summit height suggests. Plan your effort around the 757 m, not the 520 m.

How the Gradient Unfolds

An 8.84% average across 5.9 km is punishing, but averages smooth over the reality. The undulation encoded in that 237 m of extra ascent tells you the gradient swings hard around its mean — flatter recovery stretches pull the average down, which means the working ramps must sit well above 8.84% to compensate.

Expect the profile to break down roughly like this:

• Short recovery or false-flat sections where the road eases and briefly gives elevation back
• Repeated short, steep climbs stacked back-to-back rather than one continuous wall
• A steepest ramp noticeably harder than the 8.84% average, where the extra ascent concentrates

Pacing Notes

On a smooth climb, even-speed pacing works. On Hirschbichl it will wreck you. Chasing a constant speed means hammering the steep ramps and coasting the flatter parts — exactly backwards. Instead, pace to even effort: hold a steady sustainable power output and let your speed rise and fall with the gradient. Ease slightly into the flatter recovery shelves rather than surging, and cap your power on the steepest pitches so you do not blow before the summit at 1,183 m.

Know your ceiling before you start. If you have not tested recently, run the FTP estimator and set a target you can hold for the full 5.9 km — including the extra 237 m of hidden vertical.

Gearing

With sustained sections above 8.84% and steeper ramps beyond that, gearing is not optional insurance — it is the difference between spinning and grinding to a halt. Fit a compact (34-tooth) or sub-compact chainset paired with a wide-range cassette. A 34×32 gives you room; a 34×34 gives you margin on the steepest pitches. Check your setup before the ride — swapping a cassette in the car park is not a plan.

Summary

• Length: 5.9 km
• Average gradient: 8.84%
• Net elevation gain: 520 m
• Total ascent: 757 m
• Category: 1

Hirschbichl rewards riders who read the profile, not just the average. Pace to power, gear low, and respect the 237 m of ascent the net figure hides — do that, and the summit at 1,183 m is yours.
