Puerto del Acehuche cycling climb profile
Puerto del Acehuche is a short category 4 climb that rewards control more than brute force. At 2 km long with an average gradient of 4.43%, it is not a climb that should force a full survival effort, but it is long enough that a careless start can still cost time or momentum by the summit.
The climb rises from 375 m to 463 m, giving it a compact profile with 88 m of net elevation gain. The key detail is the relationship between the average gradient and the maximum gradient. With the steepest listed pitch at 4.99%, the climb does not appear to contain a major wall or a decisive ramp. That narrow spread suggests a steady uphill drag where the difficulty comes from sustaining pressure rather than responding to sharp changes in gradient.
How the gradient unfolds
Based on the available profile data, Puerto del Acehuche should be ridden as a consistent effort from bottom to top. The average sits close to the maximum, which means the road is likely to feel even rather than broken into distinct steps. There is no indication here of a steep opening section, a mid-climb sting, or a violent final ramp, so the sensible assumption is that the climb asks for rhythm.
That matters tactically. On a climb this short, the temptation is to treat the lower slopes as a launch pad and push straight above threshold. But because the gradient does not ease dramatically in the available data, any early overreach has to be paid back while the road is still rising. The better ride is a firm but measured start, then a controlled build once the summit feels close.
Pacing and gearing notes
For most trained riders, this is a climb to ride seated and efficient. Use a gear that lets you keep pressure on the pedals without grinding. Since the maximum gradient is listed below 5%, the limiting factor is unlikely to be torque. It is more likely to be whether you can hold a smooth aerobic-to-threshold effort without spiking power unnecessarily.
If using power, aim to settle quickly around the effort you can sustain for the full 2 km rather than chasing speed in the first few hundred meters. Riders working from /glossary/ftp should think of this as a controlled climbing interval: hard enough to feel purposeful, not so hard that cadence collapses before the top.
In a group, the steady gradient makes drafting and positioning relevant. A small acceleration can open space, but the climb is not steep enough to automatically punish wheelsuckers. To make a difference, the effort needs to be sustained. For solo pacing, the cleanest execution is simple: enter composed, lock into cadence, and increase only when the summit is clearly within reach.
