Arrezjoch

Arrezjoch cycling climb profile

Arrezjoch is an HC climb in Austria that asks for restraint from the first pedal strokes. The headline numbers tell the story clearly: 24.4 km long, 1717 m of net elevation gain, and an average gradient of 7.02%. That combination puts it firmly in the category of climbs where the main challenge is not a single savage ramp, but the accumulation of sustained load over a long duration.

The climb starts at 863 m and finishes at 2580 m. With 1770 m of total ascent against 1717 m of net gain, the profile is overwhelmingly uphill rather than a rolling pass with repeated descents. That matters tactically. There is unlikely to be much meaningful recovery baked into the route, so pacing mistakes made early will keep compounding all the way to the summit.

How the gradient unfolds

Without a kilometre-by-kilometre breakdown, the safest way to read Arrezjoch is as a long, steady climbing effort with severe interruptions. The 7.02% average is already demanding over 24.4 km, but the 18.4% maximum gradient changes how it should be ridden. A climb with that kind of peak pitch is not just a threshold test. It also requires enough gearing range and enough muscular freshness to handle steep ramps without being forced into repeated surges.

The key point is the gap between the average gradient and the maximum gradient. If the climb averages 7.02% but reaches 18.4%, the road cannot be treated as a metronomic steady-state effort. Even if much of it feels controllable, there are sections where torque demand will spike sharply. Those spikes are where riders who paced to the average rather than the whole profile tend to pay.

Pacing and gearing notes

Ride Arrezjoch as a long threshold-controlled climb, not as a climb to attack from the bottom. The first objective is to keep the early effort below the level that feels emotionally comfortable. On a climb of this length, that usually means letting speed look unimpressive while heart rate and breathing settle into a sustainable rhythm.

Power-based pacing should sit around a controlled climbing target rather than chasing the average speed implied by the gradient. If you use /glossary/ftp, keep the steepest ramps in reserve mentally. The 18.4% maximum pitch means there will be moments where power rises even if you are trying to stay disciplined, so the flatter or merely steady parts need to be ridden with that future cost in mind.

Gearing should be chosen for the maximum gradient, not the average gradient. A setup that feels fine on a steady 7.02% climb may become overgeared when the road kicks hard. Prioritise a low enough gear to stay seated and maintain traction on the steepest sections. If you are unsure, choose the easier climbing gear. On Arrezjoch, preserving cadence is not a comfort choice - it is part of preserving the ride.
