Puerto de Horcones

Puerto de Horcones cycling climb profile

Puerto de Horcones is a 9 km Category 3 climb in MX, rising from 1003 m to 1379 m. On paper, the average gradient of 4.17 percent makes it look manageable, and in broad terms it is. This is not a climb defined by one sustained wall. The difficulty comes from duration, rhythm, and the fact that the maximum gradient reaches 9.63 percent.

The key detail is the relationship between net elevation gain and total ascent. The climb gains 376 m net and records 377 m of total ascent, which points to a very direct uphill profile with almost no meaningful downhill relief. That matters tactically. Even if the average gradient is moderate, there is limited opportunity to coast, reset the legs, or recover without deliberately backing off.

How the gradient unfolds

With the available profile data, Puerto de Horcones should be read as a steady climb with sharper interruptions rather than a climb built around repeated descents and re-accelerations. The average grade tells you the main character: aerobic, seated, and tempo-friendly. The maximum grade tells you where riders can get caught out: short steeper pitches approaching 10 percent.

That contrast is what shapes the ride. A rider who treats the 4.17 percent average as permission to push too hard early can run into trouble when the road tips up. The steeper sections are not extreme in isolation, but on a 9 km climb they arrive after fatigue has already started accumulating. The fastest ride will usually come from smoothing those changes rather than attacking every ramp.

Pacing notes

Ride Puerto de Horcones as a controlled aerobic climb, not as a series of surges. If using power, keep the early effort comfortably under /glossary/ftp and save a little room for the steeper gradients. The average grade is low enough that speed can stay relatively high, which makes over-pacing less obvious at first. That is the trap.

A good pacing pattern is simple:

• Settle quickly into a sustainable rhythm on the lower slopes
• Avoid chasing speed when the gradient eases
• Stay seated and controlled through the moderate sections
• Use the harder ramps as places to hold effort, not lift it aggressively
• Save any real acceleration for the final part of the climb

Gearing and ride feel

Gearing should be chosen for the 9.63 percent maximum gradient, not just the 4.17 percent average. Most riders will want a climbing gear that keeps cadence from collapsing on the steepest ramps while still allowing efficient pedaling on the steadier sections.

Because the climb is almost continuously uphill, the cost of overgearing compounds. Muscling the ramps can feel fine early, but it increases muscular fatigue and makes the final kilometers harder than the raw average suggests. The better approach is to stay light on the pedals, keep torque under control, and let the climb’s consistency work in your favor.
