Termas de Copahue

Termas de Copahue cycling climb profile

Termas de Copahue is a category 2 climb that looks manageable on paper but asks a real endurance question. The headline numbers are 29.4 km at an average gradient of 3.05%, rising from 984 m to 1879 m. That combination tells you the climb is not defined by sustained steepness. It is defined by duration, altitude gain, and the need to keep pressure on the pedals for a long time without drifting into inefficient surges.

The key to understanding this climb is the gap between its length and its average gradient. At 3.05%, much of the ascent should feel rideable rather than brutally selective, but that is exactly where riders can make a pacing mistake. A climb this long invites you to ride slightly too hard early because the gradient does not immediately punish you. The cost shows up later, when the accumulated work starts to matter and the road still has a long way to go.

How the gradient unfolds

The supplied profile gives a maximum gradient of 7%, so there is no indication of extreme walls or sustained double-digit climbing. Instead, expect a climb that trends upward at a controlled average, with steeper sections that can still bite if you hit them overgeared or already above target effort.

The start elevation of 984 m and summit elevation of 1879 m show that the climb gains substantial vertical height across its 29.4 km. The listed net elevation gain is 895 m, while the supplied total ascent is 864 m. Since those two figures do not fully align, it is best to treat this as a broad climbing profile rather than a corner-by-corner gradient map. The practical conclusion is still clear: this is a long aerobic climb with limited maximum steepness, not a short power climb.

Pacing and gearing notes

Ride Termas de Copahue like a sustained endurance effort, not like a climb to attack from the base. If using /glossary/ftp as your anchor, the safest strategy is to settle into a controlled sub-threshold rhythm early and preserve the ability to respond to the 7% ramps without spiking too far above target.

Gearing should prioritize cadence control. Because the average gradient is modest, most riders will spend long stretches in comfortable climbing gears, but the maximum gradient means you still want enough range to stay seated and smooth when the road pitches up. The mistake is not lacking a huge climbing gear for the average slope. The mistake is choosing a setup that forces low-cadence grinding on the steeper sections after fatigue has accumulated.

For pacing, think in thirds:

• First third: keep the effort deliberately contained, even if the gradient feels too easy.
• Middle third: lock into a steady rhythm and avoid chasing every small change in pitch.
• Final third: use the remaining energy on the steeper ramps, not on correcting an early overpace.

Termas de Copahue is therefore less about explosive climbing ability and more about discipline. The rider who keeps the effort smooth, protects cadence, and respects the full 29.4 km will usually get more out of the climb than the rider who treats the gentle average gradient as permission to ride above plan.
