Alto de la Cueva

Alto de la Cueva cycling climb profile

Alto de la Cueva is a Category 1 climb in CL that asks for patience more than punch. On paper, the numbers are straightforward: 22.4 km at an average gradient of 5.61%, rising from 129 m to 1383 m. In practice, that combination creates a long aerobic effort where the main difficulty is not one isolated wall, but the amount of time spent climbing.

The net elevation gain is 1254 m, with total ascent listed at 1251 m, so the ride should be approached as a sustained uphill rather than a rolling climb with meaningful recovery. That matters tactically. A rider who treats the early kilometres like a moderate tempo climb can still arrive at the upper slopes with usable legs. A rider who chases every change in pitch risks turning the final third into damage control.

Gradient and effort

The 5.61% average is the defining feature. It is steep enough that drafting benefit is reduced and power-to-weight starts to matter, but not so steep that momentum disappears completely. This is the kind of gradient where small pacing errors compound quietly. You can feel comfortable riding slightly above target for a while, then pay for it once the accumulated vertical gain catches up.

The maximum gradient of 11.01% changes the gearing calculation. Even if the climb averages in the mid-single digits, there are ramps steep enough to force a clear decision: either stay seated and use a low gear, or stand briefly and accept the spike in torque. The better approach for most endurance riders is to preserve rhythm. Keep the power ceiling under control on the steeper pitches, then let the average gradient do the work over time.

How to pace it

Treat Alto de la Cueva as a long threshold-adjacent climb, not a series of attacks. If riding by power, anchor the effort to a sustainable climbing number relative to your /glossary/ftp, then give yourself a buffer for the 11.01% sections. The mistake is pacing to the average gradient while ignoring the maximum. The average tells you the climb is long and manageable. The maximum tells you where the ride can become expensive.

A simple pacing structure works well:

• First phase: settle below target and avoid chasing speed.
• Middle phase: lock into rhythm and keep cadence stable.
• Final phase: only lift the effort if the legs are still responding.

Because the climb gains 1254 m from bottom to summit, fatigue is cumulative. If the first half feels too easy, that is usually a good sign rather than a reason to force the pace.

Gearing notes

Use gearing that lets you spin comfortably on a 5.61% average while still having a bailout option for 11.01% ramps. The key is not the lowest gear in isolation, but whether you can keep pressure smooth when the gradient briefly doubles relative to the average.

Riders estimating sustainable climbing output before the ascent can use /tools/ftp-estimator, then ride Alto de la Cueva with a clear ceiling rather than guessing by feel. On a climb this long, the disciplined rider usually beats the enthusiastic one.
