Alto de Chorrillos

Alto de Chorrillos cycling climb profile

Alto de Chorrillos is a category 2 climb in Colombia that asks for patience more than explosiveness. At 16 km and an average gradient of 4.87%, it sits in that awkward middle ground where the road is rarely savage, but the effort is long enough that early optimism can become expensive before the summit.

The climb starts at 248 m and rises to 1026 m, with a listed net elevation gain of 778 m. That tells the story clearly: this is not a short punchy ramp, and it is not defined by one brutal wall. It is a sustained aerobic climb where the main difficulty is holding the right intensity for long enough.

How the gradient unfolds

The average gradient of 4.87% points to a climb that should feel mostly rideable rather than stop-start. The maximum gradient is 7.91%, which matters because it suggests the steepest sections are meaningful but not extreme. In practical terms, the climb is likely to reward a smooth seated rhythm over repeated out-of-saddle surges.

Because the maximum gradient is not dramatically higher than the average, Alto de Chorrillos should not be treated like a climb where you can soft-pedal between violent ramps. The danger is subtler. A gradient just under 5% can feel comfortable at the bottom, especially if the road opens up and speed stays relatively high. But over 16 km, riding slightly above sustainable power for too long will show up late.

Pacing and gearing notes

The smartest approach is to ride the lower slopes under control and let the climb come back to you. If you use /glossary/ftp as a pacing anchor, this is the type of ascent where drifting above threshold too early is usually a mistake unless the goal is a maximal effort and the legs are fresh.

A few practical cues:

• Keep cadence comfortable rather than forcing a big gear at the base.
• Expect the steepest gradients to reach 7.91%, so leave at least one easier gear available.
• Treat the first part as setup, not as proof that the climb is easy.
• Build effort gradually, especially if riding the full 16 km without a stop.

For riders using power, the profile suits a controlled tempo-to-threshold progression. For riders pacing by feel, breathing should stay composed early, with the hardest effort saved for the upper portion once the length has already been absorbed.

What kind of rider it suits

Alto de Chorrillos favors riders who can produce steady power and avoid unnecessary accelerations. Lighter climbers will still benefit as the road gains 778 m from start to summit, but the moderate average gradient keeps it accessible to strong endurance riders who manage cadence and intensity well.

The defining feature is not one decisive ramp. It is the accumulation: 16 km of climbing, a sustained average of 4.87%, and enough pitches near 7.91% to punish anyone who arrives under-geared or over-committed.
