Alto del Prodigio

Alto del Prodigio cycling climb profile

Alto del Prodigio is a short, sharp Category 3 climb where the difficulty is concentrated rather than cumulative. At 1.6 km in length with an average gradient of 8.63%, it is not a climb that slowly wears you down over distance. It asks for controlled force from the bottom and punishes the rider who treats it like a brief rise before the gradient has had time to bite.

The climb starts at 402 m and tops out at 538 m, giving 136 m of net elevation gain. That tells the main story: there is not much room for recovery. When a climb this short carries an average gradient this high, the effort profile is closer to a sustained threshold-plus push than a long aerobic grind.

How the gradient rides

The available profile gives the headline numbers rather than a bend-by-bend breakdown, so the safest way to read Alto del Prodigio is as a consistently demanding ascent with a ceiling that reaches 10.97%. The average of 8.63% means the road is already steep enough to require real climbing rhythm, while the maximum gradient suggests at least one section where momentum fades quickly if you are overgeared or already above your limit.

That combination matters. On a climb with a lower average and a brief steep pitch, you can often carry speed into the hardest part. Here, the base gradient is already high enough that there is limited free speed to spend. The practical consequence is simple: the first part needs to feel slightly restrained, even though the summit is close.

Pacing and effort

Do not attack the bottom unless the goal is a short maximal effort. For a sustainable ascent, ride the opening as if the steepest section is still ahead. The climb is short enough that you can lift the effort late, but steep enough that an early surge can lock the legs before the top.

A good pacing model is:

• Settle immediately into a controlled seated rhythm
• Keep breathing under control before the gradient reaches its hardest point
• Use standing only to reset torque or clear the steepest pitch
• Push over the final part once the summit is genuinely within reach

For riders pacing by power, this is the kind of climb where FTP is useful as an anchor, but the effort will often sit above steady endurance climbing intensity. The key is avoiding a spike so large that the final meters become survival rather than acceleration.

Gearing notes

Choose gearing for the 10.97% maximum, not the 8.63% average. The average tells you the climb is consistently hard; the maximum tells you whether your cadence will collapse when the road tips up. If your climbing setup only works when you are fresh, Alto del Prodigio is the type of ascent where an easier gear is worth having.

The ideal gear lets you stay seated through most of the climb without grinding. On a 1.6 km ascent, cadence discipline matters because there is not enough distance to recover from repeated high-torque accelerations. Keep the pressure smooth, protect the legs early, and spend the saved effort near the top.
