Paso de Ortiz

Paso de Ortiz cycling climb profile

Paso de Ortiz is an HC climb in CL that asks a very specific question: can you stay economical for a very long time while still having enough left for steep ramps late in the ride. On paper, 68.2 km at 4.09% looks steady rather than savage, but that average hides the real demand. The climb starts at 754 m, tops out at 3,545 m, gains 2,791 m net, and records 3,044 m of total ascent. That difference between net gain and total ascent matters because it tells you the road is not simply a clean, uninterrupted ramp from bottom to summit.

How the gradient rides

The defining feature is length. At 68.2 km, Paso de Ortiz is less about one decisive wall and more about accumulated cost. A 4.09% average over this distance means the climb will often feel manageable if ridden correctly, but every overreaction compounds. The max gradient of 12.25% is the warning label: there are sections steep enough to force a real gear choice and punish anyone who has treated the earlier gradients as free speed.

Because the total ascent is 3,044 m against 2,791 m of net elevation gain, expect the rhythm to vary. That usually changes the way the climb is paced. Any easing in the road should be used to reset pressure, eat, drink, and bring cadence back under control, not to surge. The trap on a climb like this is mistaking temporary relief for recovery. The summit still sits at 3,545 m, and the final cost is the full vertical load, not just the average gradient.

Pacing and gearing

Ride Paso de Ortiz as an endurance-controlled climb first and a threshold effort only when the road demands it. If using /glossary/ftp as an anchor, the safest approach is to stay clearly below threshold for the bulk of the ascent, especially early. The 12.25% maximum gradient means there will be moments where power rises even with discipline, so the goal is to avoid adding unnecessary spikes before those ramps arrive.

Gearing should be chosen for fatigue, not freshness. A setup that feels comfortable on moderate gradients may become restrictive once the climb has already accumulated hours of load and the road kicks up. Prioritise a low enough gear to keep seated traction and cadence through the steepest sections. If you are grinding early, the climb is already starting to dictate terms.

The best execution is patient and slightly conservative: settle into a sustainable rhythm, use flatter or easier sections to lower physiological cost, and keep enough range for the steep ramps and high summit. Paso de Ortiz rewards restraint because its difficulty is not concentrated in one place. It is spread across 68.2 km, 3,044 m of total ascent, and a profile that never lets the average tell the whole story.
