Alto del Ciruelito

Alto del Ciruelito cycling climb profile

Alto del Ciruelito is not a climb that gives much back. At 1.8 km long with an average gradient of 15.35%, it sits in that uncomfortable zone where the effort is too long to treat like a pure sprint, but too steep to ride with the rhythm of a longer mountain pass.

The key number is not just the average gradient. It is the relationship between the average and the maximum. With the steepest gradient listed at 16.57%, the climb does not appear to be defined by one isolated wall inside an otherwise moderate ascent. The average is already extremely close to the hardest listed pitch, which means the riding problem is sustained resistance rather than a single decisive ramp.

Starting at 317 m and topping out at 592 m, the climb gains 275 m from bottom to summit. Over just 1.8 km, that vertical gain explains why the profile feels compressed: there is not enough road for the gradient to relax without forcing other sections to become even steeper.

How the gradient rides

On paper, the climb should be approached as a near-continuous steep drag. The numbers suggest a bottom-to-summit effort where momentum is hard to preserve and any overgearing early will cost more than it would on a gentler climb.

This is the kind of ascent where the first few minutes matter disproportionately. If you start above threshold simply because the climb is short, the gradient gives you very few opportunities to clear the effort. A better approach is to ride the opening with restraint, settle into the steepest sustainable cadence you can hold, and only lift the effort once the summit is within reach.

For riders using power, this is a climb where pacing off feel alone can be misleading. Low speed and high torque make the effort feel urgent from the first pedal strokes. Use your /glossary/ftp as a reference, but expect the terrain to force surges simply to keep the bike moving.

Pacing and gearing notes

Use the easiest gear you have available before the gradient forces the decision for you. On a 15.35% average climb, shifting under heavy torque becomes inefficient fast, and losing cadence can turn the ascent into a series of standing accelerations.

A practical ride plan is simple:

• Start controlled, even if the climb immediately feels severe
• Keep cadence as smooth as the gradient allows
• Avoid repeated out-of-saddle spikes unless they are necessary for traction or momentum
• Save the real acceleration for the final section, not the opening ramps

Alto del Ciruelito is classified as category 1, and the numbers justify that severity. Its difficulty comes from density: a large amount of climbing packed into a very short distance, with a maximum gradient that barely exceeds an already brutal average.
