Paso de Pajaritos

Paso de Pajaritos cycling climb profile

Paso de Pajaritos is short enough to tempt riders into thinking it can be muscled over, but the numbers argue for the opposite approach. At 5.9 km with an average gradient of 11.69%, this is an HC-rated climb where the limiting factor is not patience - it is whether you can keep torque under control once the road bites.

The climb starts at 1,235 m and tops out at 1,925 m. The dataset lists 690 m of net elevation gain from bottom to summit, alongside 636 m of total ascent, but the practical takeaway is the same: the route gains height very quickly for its length. There is not enough distance here for a long, rolling rhythm to develop. Instead, Paso de Pajaritos asks for controlled force production from the lower slopes and punishes any early surge that pushes you above sustainable climbing effort.

How the gradient unfolds

With an average of 11.69%, the baseline difficulty is already high. That means even the easier sections, if they exist within the profile, are unlikely to feel genuinely restorative. The maximum gradient of 23.79% is the number that defines the pacing problem. A ramp that steep changes the climb from aerobic climbing into a strength and traction management exercise, especially if it arrives after fatigue has already built.

The best way to read this climb is as a compressed effort with repeated risk points. On a climb this steep, the difference between riding at the edge and going over it can be small. A short acceleration out of a bend, standing too aggressively, or choosing a gear that forces a low cadence can create a debt that is difficult to repay before the summit.

Pacing and gearing notes

Start below the effort you think the average gradient deserves. On paper, 5.9 km sounds manageable. In practice, 11.69% means speed will be low, cooling will be limited, and each steepening will increase muscular load quickly.

Use your easiest climbing gear from the bottom rather than waiting until the steepest ramps force the issue. The 23.79% maximum gradient is not a place to discover that cadence has collapsed. If you are pacing by /glossary/ftp, this is a climb where smoothing the effort matters more than chasing a target number every few seconds, because the road itself will create spikes.

Seated climbing should be the default when traction and cadence allow. Standing can help over the steepest pitches, but treat it as a short reset rather than a sustained tactic. The goal is to keep pressure on the pedals without turning every ramp into a maximal effort.

Paso de Pajaritos is ultimately a climb for discipline. The rider who wins the fight against the first half gives themselves a chance to handle the worst gradients near the top. The rider who attacks the opening slope like a short hill climb may spend the final kilometres surviving rather than climbing.
