Höllpass

Overview

Höllpass is a Category 4 climb in Germany, short enough to slot into a training loop but long enough to demand a real pacing plan. It runs 6.2 km from base to top, gaining 210 m net over that distance. The road starts at 493 m and tops out at 703 m, putting it firmly in the lower-mountain bracket where the challenge is rhythm rather than raw altitude.

The number that matters here is the gap between net gain and total ascent. You climb 210 m net, but the road makes you gain 231 m in total. That extra 21 m of climbing comes from short descents and dips you have to re-ascend. On paper this is a modest 3.41% average; in the legs it plays harder, because every recovery dip costs you momentum you then have to buy back. Treat the undulation as real work, not a rounding error.

How the Gradient Unfolds

A 3.41% average across 6.2 km sounds gentle, and long stretches of Höllpass genuinely are. But the 7.78% maximum tells you the effort is not evenly distributed. The steep percentage points are concentrated into short ramps, and the flatter and downhill sections drag the average down to hide them.

• Flatter, near-false-flat sections where you can hold speed and settle your breathing
• Short recovery dips that briefly point downhill before pitching back up
• Repeated low-grade rises that chip away at the legs without ever feeling decisive
• A steepest ramp near 7.78% that is the one place you may need to shift and stand

Pacing Notes

On an undulating climb like this, even-effort beats even-speed. If you chase a constant speed, you will overcook the 7.78% ramp and coast the flat sections, wasting the climb. Instead, hold a steady sustainable power output and let your speed rise on the flats and fall on the ramps. Ease off slightly into the recovery dips rather than hammering to keep the number up.

If you do not know your ceiling, run the FTP estimator first, then ride Höllpass a touch below that figure so the steep ramp does not push you into the red.

Gearing

The 7.78% maximum is well within reach of standard road gearing, but on a rolling profile you want margin so you can spin the ramps instead of grinding. A compact or sub-compact chainset paired with a wide-range cassette — think 34×32 or 34×34 — gives you a comfortable bailout for the steepest pitch while keeping cadence high on the repeated rises. Check your setup before the ride so you are not caught in the wrong gear on the one ramp that bites.

Summary

• Length: 6.2 km
• Average gradient: 3.41%
• Maximum gradient: 7.78%
• Net elevation gain: 210 m
• Total ascent: 231 m
• Category: 4

Höllpass rewards a rider who respects the undulation. Ride it on even effort, gear for the 7.78% ramp, and the 21 m of hidden climbing will feel like part of the plan rather than a surprise.
