Alto del Morrón

Alto del Morrón cycling climb profile

Alto del Morrón is a long Category 1 climb where the headline number is not the maximum gradient, but the duration. At 26.3 km with 1,222 m of net elevation gain, this is the kind of ascent that rewards control far more than aggression. The average gradient of 4.65% can make it look manageable on paper, but that number is spread across a very long effort, and the total ascent of 1,359 m tells you the road is not simply a clean, uninterrupted ramp from bottom to top.

The climb starts at 585 m and tops out at 1,807 m, so the work is substantial even before accounting for the extra climbing hidden in the profile. The difference between net gain and total ascent suggests there are sections where the road relents or gives back elevation before asking for it again. That matters tactically: any easier stretch should be used to reset pressure, not to chase speed.

How the gradient unfolds

With a 4.65% average and a maximum gradient of 9.53%, Alto del Morrón sits in the awkward middle ground between a tempo climb and a true mountain grind. The average says the climb is mostly rideable at a steady rhythm, while the maximum gradient says there are sharper pitches capable of disrupting that rhythm if you arrive over-geared or already above threshold.

The practical reading is simple: expect a climb that can feel deceptively calm early, then gradually becomes more costly because of accumulated time under load. A rider who treats the lower slopes like a rolling road effort will pay later, especially if the steeper sections arrive after fatigue has already started to bite.

This is not a climb to pace off emotion. It is a climb to pace off repeatability. If you know your /glossary/ftp, the early target should sit clearly below the level you would use for a short climb. The goal is to preserve the ability to respond when the gradient moves toward its maximum, rather than needing to survive it.

Pacing and gearing notes

The best approach is to divide Alto del Morrón mentally into two demands: the long aerobic drag and the short, steeper interruptions. On the steadier sections, keep torque low and cadence comfortable. Do not force a big gear just because the average gradient looks modest. Over 26.3 km, small over-pacing errors compound quickly.

For gearing, the key is having enough range for the 9.53% maximum gradient without turning those pitches into muscular efforts. A bailout gear is useful here, not because the climb is brutally steep throughout, but because the long duration makes the steepest ramps arrive with fatigue already present.

If riding it as a hard effort, cap the opening portion and let the climb come back to you. If riding it for endurance, treat the easier sections as recovery windows and the steeper sections as controlled surges. The profile favors riders who can keep pressure consistent, manage variability, and resist the temptation to make a Category 1 climb feel easy too early.
