The climb
Gradient profile
Overview
Hochtor is a hors catégorie (HC) climb in Austria, topping out at 2,562m. It runs 16.9km from a start elevation of 1,143m to a summit at 2,562m, delivering a net elevation gain of 1,419m. At an average gradient of 8.38%, this is a sustained, high-mountain effort that sits firmly in the hardest category the sport recognizes.
The number that reshapes your expectations is total ascent: 2,096m against a net gain of 1,419m. That 677m gap means the road does not climb in a single clean line — you give back roughly 677m of elevation to descents and dips along the way, then have to reclaim it. In practice, the real climbing is closer to 2,096m of vertical, and every metre lost on a downhill is a metre you pay back on a steeper ramp. Budget your legs for the total ascent, not the net figure.
How the Gradient Unfolds
The 8.38% average is an accounting trick. Because 677m of the profile is descent and re-climb, the average is dragged down by flatter and downhill sections — which means the climbing pitches are meaningfully steeper than 8.38% to compensate. Expect the gradient to swing hard rather than hold steady.
- Flatter and recovery sections where the road eases or tips downhill — do not waste energy here, but do refuel and reset.
- Repeated short climbs stitched together by the descents, so you re-accelerate and re-load your legs several times over 16.9km.
- The steepest ramp reaching 32.23% — a wall-like pitch that demands your lowest gear and full attention.
Pacing Notes
On a smooth climb, even-effort and even-speed pacing nearly converge. Hochtor is not smooth. With this much undulation, chase even effort, not even speed: hold your sustainable power output steady through the steep pitches and let your speed rise freely on the flatter and downhill sections rather than soft-pedalling to a target pace. Surging to hold speed on the 32.23% ramp will cook you; drifting on the descents wastes free time. Know your ceiling before you start — the FTP estimator will tell you the wattage you can defend across a climb this long.
Gearing
The steepest gradient governs your setup. At 32.23%, a standard road compact is not enough — fit a compact or sub-compact chainset paired with a wide-range cassette, at minimum 34×32 and ideally 34×34, so you can keep the pedals turning on the wall without lurching out of the saddle. Check your chainset and cassette before the ride; discovering you are over-geared on a 30%-plus ramp at 2,500m of altitude is not a fixable problem mid-climb.
Summary
- Length: 16.9km
- Average gradient: 8.38%
- Maximum gradient: 32.23%
- Net elevation gain: 1,419m
- Total ascent: 2,096m
- Category: HC
Hochtor is a full HC test: 16.9km, a summit at 2,562m, and 2,096m of real climbing hidden behind a modest-looking average. Pace to effort, gear for the steepest ramp, and respect the undulation and it rewards you at the top.
