Paso Pinyerro cycling climb profile
Paso Pinyerro is a category 2 climb that asks for patience more than violence. At 15.2 km and an average gradient of 4.03%, it is not defined by constant steepness, but by duration, elevation gain, and the need to stay efficient across a long uphill effort.
The climb starts at 1062 m and tops out at 1675 m, gaining 613 m net. The total ascent is 655 m, which tells you the road is not simply one uninterrupted ramp from bottom to summit. There is a small amount of extra climbing beyond the net gain, so expect the effort to have some variation rather than a perfectly steady metronome feel.
Gradient and ride feel
The headline average of 4.03% can make Paso Pinyerro look gentle on paper, but that number needs context. Over 15.2 km, even a moderate gradient becomes a meaningful aerobic load, especially because the maximum gradient reaches 10.35%. That contrast matters. The climb is likely to reward riders who can hold a controlled tempo on the easier ground while staying composed when the road kicks up.
Because the available profile gives the overall numbers rather than a kilometer-by-kilometer breakdown, the smart assumption is simple: do not ride the average gradient as if it describes every section. A 4.03% climb with pitches above 10% is a different problem from a smooth 4% drag. The steepest sections will demand either a short lift in power or a deliberate downshift in cadence and speed. Burning matches there is the easiest way to turn the final part of the climb into damage control.
Pacing strategy
Treat Paso Pinyerro as a long threshold-adjacent climb rather than a punchy ascent. The first priority is keeping the early effort capped. If you ride by power, settle below the number you would use for a short climb and let the duration do the work. If you ride by feel, the opening should feel almost too controlled. That is usually the correct sensation on a climb long enough for poor pacing to compound.
The key tactical mistake is chasing speed on the easier gradients and then forcing the ramps. Instead, use the lower-gradient sections to stabilize breathing and cadence, then absorb the steeper pitches without spiking far above your sustainable effort. The climb’s category 2 rating fits that profile: not extreme, but substantial enough that pacing discipline decides the quality of the ride.
For riders using /glossary/ftp as a reference, Paso Pinyerro is the kind of climb where repeatable aerobic power matters more than a single surge. If you are unsure of your current number, an estimate from /tools/ftp-estimator is more useful here than guessing and riding the first half too hard.
Gearing notes
Bring gearing that lets you stay seated and smooth when the gradient reaches 10.35%. The average may suggest a moderate setup, but the maximum gradient argues for a bailout gear, especially if the climb comes late in a ride or after previous elevation gain.
The best setup is not the one that feels efficient on the 4% sections. It is the one that prevents you from grinding when the road briefly becomes much steeper. Keep cadence available, protect your legs, and let the climb’s length decide the effort rather than one steep ramp deciding it for you.
