Alto del Obispo

Alto del Obispo cycling climb profile

Alto del Obispo is a category 1 climb built less around savage average gradient and more around duration. At 25.5 km, with 1,368 m of net elevation gain, it is long enough that pacing errors made early have time to compound. The average gradient of 5.37% can make it look manageable on paper, but the 14.8% maximum gradient changes how it should be ridden.

The key point is that this is not a short, punchy climb where you can bluff your way through on repeated accelerations. It starts at 1,094 m and tops out at 2,462 m, so the ride is defined by sustained elevation gain from bottom to summit. Total ascent is 1,369 m, almost identical to the net gain, which suggests the route is effectively a continuous uphill effort rather than a climb broken up by meaningful descents.

How the gradient unfolds

The available profile data does not give kilometre by kilometre gradients, so the honest read is macro rather than segment-specific. Across the full 25.5 km, the climb averages 5.37%, which points to a mostly steady ascent. But the maximum gradient of 14.8% shows that the average is hiding steeper ramps somewhere on the climb.

That combination matters. A climb averaging just over 5% can invite riders to settle into a tempo that feels sustainable early on, especially if the opening slopes are not immediately severe. But on a climb this long, any section near the maximum gradient will demand a much higher torque output. If you arrive at those ramps already riding above threshold, the cost is not just momentary discomfort. It can force you into recovery mode while the road is still going up.

Think of Alto del Obispo as a long aerobic climb with anaerobic interruptions. The average gradient rewards rhythm, while the steepest pitches punish overgearing and impatience.

Pacing and gearing notes

Pace this climb from the total duration implied by 25.5 km, not from the relatively moderate 5.37% average. The right strategy is controlled pressure early, then reassess once the cumulative gain starts to bite. If riding by power, keep the baseline effort below your true climbing limit and save room for the 14.8% ramps. If you need a reference point, use your sustainable climbing power rather than chasing speed, since gradient changes will distort pace quickly. See /glossary/ftp for how that anchor should guide long climbs.

Gearing should be chosen for the maximum gradient, not the average. A setup that feels efficient at 5.37% can become too heavy when the road pitches toward 14.8%, especially late in a 1,368 m net gain effort. The practical goal is simple: have a low enough gear to keep cadence from collapsing on the steepest sections without spiking effort beyond what you can recover from.

The best ride here is patient. Hold back when the climb feels easier than expected, protect cadence when the gradient kicks, and let the length do the sorting. Alto del Obispo is not defined by one number. It is the interaction between distance, steady gain, and steep ramps that makes it demanding.
