Alto del Gaucho

Alto del Gaucho cycling climb profile

Alto del Gaucho is a category 1 climb built around sustained duration rather than a single savage average gradient. The road runs for 23.2 km, starts at 418 m, and tops out at 1685 m. That gives it 1267 m of net elevation gain at an average gradient of 5.46%.

The key number is not just the average. It is the gap between the average gradient and the maximum gradient of 18.05%. A climb averaging 5.46% can invite riders to settle into a comfortable tempo early, but a maximum this high changes the pacing problem. You are not only managing a long aerobic effort. You are also protecting yourself against steep ramps that can push you well above sustainable climbing power if you arrive overgeared or already carrying too much fatigue.

How the gradient should feel

With only the headline profile available, the safest way to read Alto del Gaucho is as a long climb with a moderate overall slope and severe peak gradients. From the bottom, the climb asks for restraint. The 23.2 km length means any early surge has a long repayment period, and the total vertical change is large enough that small pacing errors compound.

The 5.46% average suggests there will be sections where rhythm matters more than brute force. But the 18.05% maximum means the climb cannot be treated like a steady diesel effort from bottom to summit. Any ramp near that maximum will change the physiological cost quickly: cadence drops, torque rises, and the effort can shift from controlled threshold riding into repeated anaerobic spikes.

Pacing and gearing notes

Do not gear for the average. Gear for the steepest number on the profile. If your easiest gear only feels comfortable at 5.46%, it may be too heavy when the road pitches toward 18.05%. A compact or subcompact setup with a wide-range cassette is the sensible choice for most riders, especially if the climb comes after previous work or in warm conditions.

Pacing should be anchored below your sustainable climbing effort for the opening phase. Use the early kilometres to find pressure on the pedals without chasing speed. If you know your /glossary/ftp, keep the baseline controlled and save matches for the steepest ramps. Riders without recent test data should use /tools/ftp-estimator before building a pacing target.

The practical rule is simple: keep the climb aerobic whenever the gradient allows it, then absorb the steep sections without fighting the bike. On Alto del Gaucho, the rider who respects the length and gears for the maximum gradient is far more likely to finish strongly than the rider who treats 5.46% as the whole story.
