Alto del Sauce

Alto del Sauce cycling climb profile

Alto del Sauce is a long, controlled climb rather than a wall. The headline number is 16 km at an average gradient of 3.87%, which tells you the effort is more about durability and discipline than pure climbing violence. But the maximum gradient of 11.73% matters, because it means the climb is not simply a steady tempo drag from bottom to summit.

The road starts at 205 m and reaches 826 m, giving a net elevation gain of 621 m. That rise over 16 km creates a profile where the average gradient can feel manageable on paper, but the real cost comes from how the steeper sections interrupt rhythm. A rider who treats the entire climb like a smooth sub-4% ascent risks arriving at the harder ramps already overextended.

How the gradient should feel

With an average of 3.87%, much of Alto del Sauce should be rideable at a seated endurance or tempo effort for a trained cyclist. The climb rewards momentum: staying aero enough when the gradient is gentle, keeping pressure on the pedals, and avoiding the temptation to surge every time the road tilts up.

The key complication is the 11.73% maximum gradient. Even if those ramps are short, they change the pacing equation. On a climb this long, spikes above threshold are expensive because they create lactate and muscular fatigue that have to be carried through the remaining kilometres. The fastest ride is likely not the one with the highest early power, but the one with the smallest number of unnecessary accelerations.

Pacing strategy

Start conservatively. A 16 km climb gives plenty of time to make up speed, but very little forgiveness if you go too deep early. Ride the opening part below your sustainable climbing effort, then let the effort rise only once the road and your breathing have settled.

Use the average gradient as a warning, not a guarantee. A sub-4% average can hide sharp pitches, and the listed 11.73% maximum confirms that Alto del Sauce has moments where gearing and torque management matter. If riding by power, anchor the climb around a controlled tempo and allow only brief, deliberate rises when the gradient forces them. If riding by feel, keep the steepest sections at a pressure you can recover from without needing to back off completely afterward. For reference, this is exactly where knowing your /glossary/ftp helps turn pacing from guesswork into execution.

Gearing notes

Choose gearing for the steepest ramp, not the average gradient. The climb may average 3.87%, but an 11.73% section can quickly turn a moderate ascent into a low-cadence grind if the easiest gear is too ambitious. A compact setup or generous climbing cassette is the safer choice for most riders, especially if the goal is to keep cadence stable and avoid burning matches out of the saddle.

The practical target is simple: preserve rhythm on the easier gradients, stay seated as long as possible on the ramps, and keep enough reserve to ride the final part with pressure rather than survival mode.
