Arltörl

Arltörl cycling climb profile

Arltörl is not complicated on paper, which is exactly what makes it so demanding. The climb is 11.1 km long, averages 9.91%, and is rated HC. That average tells the story better than any marketing language could: this is a sustained climbing effort where the baseline difficulty is already close to double digits.

Starting at 827 m and topping out at 1,923 m, Arltörl gains 1,096 m net from bottom to summit. The listed total ascent is 1,069 m, but either way the practical takeaway is the same. You are not dealing with a rolling alpine road where the average is softened by descents or long false flats. The numbers point to a climb where elevation gain is stacked steadily across the full distance.

How the gradient unfolds

With only the overall profile data available, the honest reading is that Arltörl should be approached as a near-continuous steep climb rather than a climb with clearly defined easy and hard sectors. The average gradient of 9.91% is already severe, while the maximum gradient of 12.92% sits only a few percentage points above that average. That gap matters.

On many climbs, a high maximum gradient can be a short sting that distorts an otherwise manageable ascent. Here, the maximum does not look like an outlier compared with the average. Instead, it suggests a road that lives in a narrow but punishing range: steep most of the time, occasionally steeper, and rarely forgiving enough to reset the legs.

That makes Arltörl a rhythm climb only if your rhythm is sustainable at high torque. If you start above threshold because the first slopes feel manageable, there is not enough statistical evidence of recovery later to count on getting that effort back.

Pacing and gearing notes

The right pacing strategy is conservative early, controlled through the middle, and only opportunistic near the summit. On an 11.1 km climb averaging 9.91%, the cost of riding the lower slopes too hard compounds quickly. This is the kind of ascent where a few minutes above your sustainable climbing power can turn the final third into damage control.

Use your /glossary/ftp as a ceiling, not a target, unless you are racing the climb specifically. If your current threshold is uncertain, estimate it before building a pacing plan with /tools/ftp-estimator. For most riders, the goal should be to keep cadence from collapsing when the road approaches the 12.92% maximum gradient.

Gearing should be chosen for the average, not the best-case scenario. A climb that averages almost 10% over 11.1 km demands a low enough gear to stay seated and smooth when fatigue arrives. If the easiest gear only feels comfortable at the base, it is probably not easy enough for Arltörl.

Bottom line

Arltörl is an HC climb because it combines length, altitude gain, and sustained steepness without relying on a single headline ramp. The difficulty is cumulative. Ride it like a long threshold effort on a steep road, respect the average gradient from the first kilometer, and save the aggression for the point where the summit is close enough that pacing mistakes no longer have time to fully punish you.
