Untersulzbachtörl

Untersulzbachtörl cycling climb profile

Untersulzbachtörl is a proper endurance climb before it is a pure gradient test. The headline numbers set the tone: 31 km, 1,735 m of net elevation gain, and an average gradient of 5.59%. That average can look manageable on paper, but over this distance it becomes the trap. A rider who treats it like a medium-length tempo climb will start paying for that decision long before the summit at 2,505 m.

The profile starts at 770 m and climbs into a very large vertical block. The important detail is that total ascent is 1,846 m, which is 111 m more than the net gain. That tells you the road is not simply a perfectly even ramp from bottom to top. Any easing, flattening, or loss of height has to be earned back later, and on a climb this long that makes rhythm harder to hold.

How the gradient unfolds

With only the core profile data, the honest read is that Untersulzbachtörl should be paced as an irregular long climb rather than a steady metronomic ascent. The 5.59% average points to long sections where seated tempo is realistic, but the maximum gradient of 11.74% changes the way the climb should be approached. Those steeper pitches are more than twice the average, which means the hardest moments are likely to force a clear change in torque, cadence, or power output.

That contrast is what defines the ride. The climb gives enough moderate gradient to encourage speed and pressure on the pedals, but it also has enough severity to punish riders who ride above themselves early. On an HC climb with 31 km of road, the decisive limiter is rarely one single steep ramp. It is the accumulation of repeated accelerations, gear changes, and small power spikes layered on top of a long aerobic effort.

Pacing and gearing

The right approach is conservative early and disciplined through the middle. Ride the lower slopes by effort, not by speed, and keep the power below the level that would feel sustainable for a shorter climb. If you use /glossary/ftp as a pacing anchor, this is a climb where avoiding early surges matters more than proving fitness in the first half.

Gearing should account for the 11.74% maximum, not just the 5.59% average. A setup that feels comfortable on a steady 6% climb may become restrictive when the road steepens, especially after a long period of climbing. Prioritise a low enough gear to stay seated and keep cadence under control on the steepest ramps.

The main tactical mistake is to let the average gradient define the effort. Untersulzbachtörl is long enough, high enough, and uneven enough that the smart ride is built around restraint. Save the hardest efforts for the upper part, because the numbers say this climb is less about one dramatic wall and more about how well you manage fatigue across a very large ascent.
