Henlabjoch

Henlabjoch cycling climb profile

Henlabjoch is a Category 2 climb in Austria that is more subtle than its headline average suggests. The climb runs for 21.2 km, starting at 660 m and topping out at 1324 m, with a listed net elevation gain of 664 m. On paper, the 3.13% average gradient makes it look controlled rather than brutal, but the 13.93% maximum gradient is the number that matters for how it actually rides.

This is not a climb where the average tells the whole story. A road that averages 3.13% over 21.2 km but still reaches 13.93% has to be uneven. The steepest gradients cannot define the entire ascent, so they are balanced by easier sections elsewhere. That makes Henlabjoch less about surviving one continuous wall and more about managing changes in torque, cadence, and effort across a long climb.

How the gradient unfolds

From bottom to summit, the practical story is duration first, sharp ramps second. The climb gains height gradually across a long distance, so the main risk is not being overmatched by the average gradient. It is being drawn into repeated accelerations whenever the road kicks up.

The 13.93% maximum gradient changes the pacing problem. On a climb with this average, any section near the maximum is likely to feel disproportionately hard because it arrives after easier gradients have encouraged a higher tempo. If you ride the lower-gradient parts too close to /glossary/ftp, the steep pitches become expensive very quickly.

There is also a small data note worth respecting. The supplied profile lists 664 m of net elevation gain from the 660 m start to the 1324 m summit, while total ascent is listed at 648 m. Since those fields conflict, the safest interpretation is to base pacing on the length, start and summit elevations, average gradient, and maximum gradient rather than over-reading the ascent total.

Pacing and gearing notes

Henlabjoch rewards restraint. Settle into a sustainable rhythm early and treat the easier gradients as recovery or efficiency zones, not places to chase speed. The climb is long enough that small over-threshold efforts can compound, especially if they are forced by the steeper ramps.

Use a gear that lets you stay seated and keep pressure smooth when the gradient rises toward the maximum. You do not need to gear the entire climb as if it averages double digits, but you do need a low enough option that the steepest pitches do not force grinding or standing surges.

For riders pacing by power, the best approach is to keep the main body of the climb controlled and allow only brief, deliberate rises on the steepest sections. For riders pacing by feel, the cue is simple: if the shallow sections already feel like work, the 13.93% ramps will cost more than they should.

Henlabjoch is a climb to ride with patience. Its average gradient invites confidence, but its maximum gradient punishes sloppy pacing.
