Paso de Botello

Paso de Botello cycling climb profile

Paso de Botello is a compact but severe climb. On paper, the headline is simple: 1.8 km at an average gradient of 12.84%, starting at 582 m and topping out at 814 m. That makes it short enough to tempt riders into overcommitting early, but steep enough that any pacing mistake gets expensive quickly.

The key detail is the relationship between the average gradient and the maximum gradient. The climb averages 12.84%, while the listed maximum is 13.25%. That narrow gap tells you this is not a climb defined by one savage wall inside an otherwise manageable road. It is the opposite: the difficulty appears to come from sustained steepness, with very little statistical sign of relief.

How the gradient rides

With only 1.8 km to cover, Paso de Botello is not a long endurance climb, but it still demands control. A climb at this gradient changes the cost of every acceleration. If you surge above threshold too early, the road gives you limited room to settle back into rhythm because the average stays close to the maximum.

The profile lists 232 m of net elevation gain and 183 m of total ascent. That discrepancy is worth noting if comparing files or route data, but it does not change the practical read: this is a steep, Category 2 effort where traction, cadence, and pacing matter more than outright speed.

Pacing strategy

Ride the opening as if the summit is farther away than it looks. The biggest mistake on a 1.8 km climb at 12.84% is treating it like a short punch and going straight into the red. The better approach is to lock into a hard but controlled effort from the bottom, then only lift the intensity once the summit is clearly within reach.

For riders pacing by /glossary/ftp, this is likely to feel closer to an extended anaerobic or VO2-style effort than a steady alpine climb. The limiter will often be muscular fatigue as much as aerobic capacity, especially if cadence drops and each pedal stroke becomes a grind.

Gearing and technique

Bring your easiest climbing gear. The average gradient is already in the range where poor gearing turns pacing into survival, and with the maximum only slightly higher than the average, there is no obvious place to recover if you run out of cadence.

Stay seated where possible to preserve traction and keep the power delivery smooth. Standing can help reset the legs, but on a climb this steep and short, repeated out-of-saddle surges can push the effort above what is sustainable. The cleanest ride is usually the simplest one: choose the gear early, hold cadence as well as the slope allows, and save the final lift for the last section.
