El Palu

Overview

El Palu is a long, moderate ascent that rewards rhythm over raw power. Over 12.8 km it climbs from a base at 647 m to a summit of 1144 m, a net gain of 497 m at an average gradient of 3.87%. On paper that average reads gentle, and for much of the climb it is — this is a road you can ride seated, at tempo, watching the metres tick by. But the 11.37% maximum gradient tells you the average is smoothing over some sharper pitches. Rated category 3, El Palu sits below the brutal category 1 and HC monsters, yet its length means it still demands patience and a plan.

How the Gradient Unfolds

The gap between the 3.87% average and the 11.37% maximum is the whole story here. A climb that never left the low single digits would feel metronomic; El Palu instead mixes long shallow drags with occasional ramps that spike toward that 11.37% figure. Note too the small difference between the 497 m net elevation gain and the 482 m of total ascent — the profile is almost entirely uphill, with barely any false-flat or downhill relief to reset your legs. That means once you start climbing at 647 m, you keep climbing, more or less continuously, until the 1144 m top. Expect the steep sections to arrive in short bursts against an otherwise steady backdrop, so read the road ahead and shift early rather than getting caught grinding.

Pacing Notes

With 12.8 km to cover, the mistake is starting too hard on the shallow lower slopes and paying for it when the gradient bites. Anchor your effort to your sustainable power. Riding at or just under your FTP for the length of El Palu is realistic for a fit rider, but on the ramps toward 11.37% you'll briefly push over it — that's fine, provided you settle back down afterward. If you don't know your threshold, run the numbers through the FTP estimator before you commit to a target. Break the climb into thirds mentally: settle in over the first third, hold steady through the middle, and only lift the effort once you can see the 497 m of gain is nearly banked. Fuel and drink on the shallow stretches, because the steep pitches are no place to reach for a bottle.

Gearing

For a climb averaging 3.87% you won't need your smallest gear most of the time, but the 11.37% ramps change the calculation. A compact chainring with a 34×32 low gear is a sensible baseline and will get most riders up El Palu comfortably. If you climb at a lower cadence, carry extra weight, or simply want insurance against those steeper pitches after 12.8 km of accumulated fatigue, a 34×34 gives you meaningful headroom to keep spinning rather than grinding. Erring toward the easier ratio costs you almost nothing on the flatter drags and protects your legs where it matters.

Summary

El Palu is a climb of endurance rather than explosiveness: long, steadily uphill, and manageable if you respect its length and the sting of its steepest ramps. Pace it patiently, gear generously, and the 1144 m summit comes to you.
