Alto de los Corrales

Alto de los Corrales cycling climb profile

Alto de los Corrales is a category 1 climb in AR, and the headline number that matters is the length. At 29.6 km, this is not a climb you can treat like a short threshold test. The average gradient is 4.84%, which sounds manageable on paper, but that number is spread across a very long effort and includes a maximum gradient of 19.54%. That combination changes how it should be ridden.

The climb starts at 522 m and tops out at 1956 m, for a net elevation gain of 1434 m. That tells you the effort is not defined by one savage wall, but by accumulation. The road keeps taking altitude for a long time, and even if much of the climbing sits near a tempo-friendly grade, the steepest pitches are sharp enough to punish anyone riding too close to the limit early.

How the gradient rides

With only the supplied profile numbers, the exact placement of the steepest ramps is not known. That matters for pacing. You should assume the climb can change character without warning: steady enough to invite overconfidence, but with sections steep enough to force a real torque demand.

A 4.84% average over 29.6 km usually rewards rhythm, seated climbing, and patience. But the 19.54% maximum means the average is misleading if used as the only guide. The practical takeaway is simple: ride the main body of the climb below your ceiling, because any near-maximal surge on a steep ramp will cost more here than it would on a shorter climb.

Pacing and gearing

The best strategy is controlled restraint. Settle into a sustainable climbing output early, then protect your cadence when the road kicks up. If you are using /glossary/ftp as your anchor, this is the kind of climb where riding just under your hard sustainable limit is usually smarter than trying to hold the average gradient as if it were uniform.

Gearing should account for the maximum gradient, not just the average. A low gear is useful even for strong riders, because the steepest sections can push cadence down and turn the effort muscular. Once cadence collapses, the climb becomes harder to recover from, especially with so much distance still to cover.

The key is to treat Alto de los Corrales as a long endurance-climbing problem with intermittent steep stress. Stay smooth on the moderate sections, avoid ego-driven surges, and keep enough margin to absorb the hardest ramps when they arrive.
