Alto de las Minas

Alto de las Minas cycling climb profile

Alto de las Minas is not a climb that lets you settle in gradually. On paper, it is only 3.8 km long, but the average gradient of 17.09% changes the entire riding problem. This is an HC-rated climb because the difficulty is compressed. There is very little distance available to recover, correct a pacing mistake, or ride your way back into control once the slope has pushed you over threshold.

The climb starts at 311 m and tops out at 959 m, with a listed net elevation gain of 648 m. That tells you the main story before the road is even divided into sections: this is a sustained fight against gravity rather than a long aerobic build. With a maximum gradient of 24.24%, the hardest pitches are steep enough that traction, cadence, and front-wheel control start to matter alongside raw power.

How the gradient shapes the ride

Because the average sits above 17%, the defining feature is not a single wall near the top or one isolated ramp. The whole climb is severe. Even if the road briefly eases, the baseline demand remains high enough that it will still feel like climbing under pressure.

That matters tactically. On a more regular alpine-style climb, a rider can often ride slightly above /glossary/ftp on steeper bends and recover on flatter portions. Here, the average gradient leaves much less room for that pattern. If you surge early, the cost shows up quickly because there is no meaningful low-gradient terrain baked into the profile.

The 24.24% maximum also changes how you should think about momentum. Entering the steepest ramps already loaded from the average gradient means you cannot simply muscle through them repeatedly. The better approach is to protect cadence and keep the effort just below the point where each pedal stroke becomes a grind.

Pacing and gearing notes

Start easier than the climb feels like it allows. That sounds counterintuitive on something this steep, but the opening effort sets the ceiling for the rest of the ascent. If you are already fighting the bike in the first part, the upper slopes will be dictated by survival rather than pacing.

Use your easiest climbing gear and choose gearing more conservatively than you would for a longer, steadier climb. The goal is not speed early. The goal is preserving enough cadence to keep producing power when the gradient pushes toward its maximum.

Practical cues:

• Stay seated when possible to manage traction and keep power delivery smooth.
• Stand only when the gradient forces it or when cadence is collapsing.
• Keep the upper body quiet, especially on the steepest ramps.
• Pace by sustainable pressure, not by chasing speed, because speed will drop sharply on this gradient.

For riders using power, Alto de las Minas is a reminder that /glossary/ftp is only part of the equation. At gradients this steep, muscular endurance and gearing can become the limiter before the aerobic system fully does. If you are estimating targets beforehand, use a conservative number from /tools/ftp-estimator and assume the gradient will make the effort feel harder than the duration suggests.
