Ala-Bel Pass

Ala-Bel Pass cycling climb profile

Ala-Bel Pass is a category 1 climb in KG built around one simple problem: duration. The headline numbers are 23.7 km at 5.29%, starting at 1916 m and finishing at 3170 m. That makes it less about surviving one savage wall and more about managing a long, accumulating effort where small pacing errors can become expensive before the summit.

The net elevation gain is 1254 m, which tells you the road is doing real work from bottom to top. The average gradient is moderate on paper, but it is still steep enough to keep pressure on the pedals for a long time. With a maximum gradient of 10.41%, the climb also has steeper sections that will punish anyone who rides only to the average.

How the gradient unfolds

The available profile data does not break the climb into named ramps or kilometre-by-kilometre sectors, so the most useful way to read Ala-Bel Pass is as a long sustained ascent with sharper changes inside it. Over 23.7 km, an average of 5.29% means the climb should feel mostly aerobic if paced correctly, but the 10.41% maximum gradient changes the gearing requirement.

That matters because a climb with this length and this max gradient creates two separate demands. The base demand is holding a controlled climbing output for a long time. The secondary demand is absorbing the steeper pitches without spiking too far above threshold. If you treat every harder section as a chance to accelerate, the later part of the climb becomes less about fitness and more about damage control.

The altitude numbers also shape the ride. Starting at 1916 m and topping out at 3170 m, the climb finishes high enough that pacing discipline becomes more important as the road rises. Even if the gradient stays manageable, the cost of repeated surges usually grows later in the climb.

Pacing and gearing notes

Ala-Bel Pass should be ridden from the bottom with the summit in mind, not the first steep ramp. The correct effort is likely a controlled tempo or sub-threshold rhythm for most riders, with enough margin to handle the sections that approach 10.41% without grinding.

Practical approach:

• Start below your target climbing effort for the opening phase, because 23.7 km gives plenty of time for early enthusiasm to turn into fatigue.
• Use the 5.29% average as a guide to the climb's general load, but choose gearing for the 10.41% maximum gradient.
• Keep cadence protected on the steeper sections. If you are forced into low-cadence grinding early, the climb will cost more muscularly than it needs to.
• Avoid repeated power spikes above /glossary/ftp unless you are near the top or riding tactically. On a climb this long, those spikes compound quickly.

The best setup is a climbing-friendly gear range that lets you stay seated and smooth when the gradient tightens. Ala-Bel Pass is not defined by one brutal statistic. It is defined by the combination of length, steady gain, high summit, and enough steepness to make poor pacing visible.
