Alto de Los Cruces cycling climb profile
Alto de Los Cruces is a compact but demanding category 2 climb in CO: 5.6 km at an average gradient of 7.06%, rising from 295 m to 687 m. That gives it the feel of a climb where the effort becomes serious quickly. It is not long enough to reward a slow, exploratory start, but it is steep enough that riding the opening too hard can turn the final part into damage control.
The key number is the gap between the average gradient and the maximum gradient. An average of 7.06% already requires sustained climbing power, while a maximum of 11.58% means there are sections steep enough to force a real change in torque. The profile data does not provide a corner by corner breakdown, so the safest interpretation is that the climb should be ridden as a steady threshold-style effort with readiness for sharper ramps, not as a smooth tempo ascent.
How the gradient rides
Across 5.6 km, the climb gains 392 m from start to summit, with 368 m listed as total ascent. However you parse that elevation data, the practical takeaway is the same: there is very little room to recover once the road tilts up. A climb averaging just over 7% over this distance keeps pressure on the legs almost continuously.
The maximum gradient of 11.58% matters because it changes the physiology of the effort. If you ride the 7.06% average as though it is the hardest part, the steeper pitches will push you above sustainable power. That is where riders start burning matches they still need near the top. On a climb like this, the rider who looks slightly restrained early is often the rider who can keep producing power when the gradient bites.
Pacing strategy
Treat Alto de Los Cruces as a controlled climbing effort, not a series of attacks against the gradient. The smartest pacing is to settle just below your sustainable climbing power early, then allow short rises above it only when the road forces the issue. If you ride by /glossary/ftp, this is the type of ascent where discipline matters more than enthusiasm.
A useful approach:
- Start with restraint through the lower slopes, especially before you know where the steeper ramps arrive.
- Keep cadence smooth on the average-gradient sections rather than chasing speed.
- On pitches near the 11.58% maximum, shift early and accept a short rise in effort without turning it into a full surge.
- Save the final acceleration for when the summit is clearly within reach, not when the climb first feels manageable.
Gearing notes
Because the climb averages 7.06% and reaches 11.58%, gearing should be chosen for the steepest ramps, not the average. A gear that feels efficient at 7% can become too heavy when the road tips into double-digit territory. The aim is to preserve seated climbing rhythm and avoid being forced into low-cadence grinding before the top.
For stronger riders, Alto de Los Cruces is a sustained power test. For less experienced climbers, it is primarily a pacing test. Either way, the climb rewards patience: hold back just enough early, keep the gear light enough to manage the steepest sections, and let the summit come to you rather than trying to force the climb open too soon.
