Alto de Tochupa

Alto de Tochupa cycling climb profile

Alto de Tochupa is an HC climb in Colombia built around duration more than raw average gradient. On paper, 36.2 km at 4.89% can look manageable, but that number is doing a lot of smoothing. The climb rises from 1,364 m to 3,135 m, gaining 1,771 m from bottom to summit, with 1,798 m of total ascent. That small gap between net gain and total ascent tells you the road is essentially committed to going uphill, with very little relief baked into the profile.

The practical reading is simple: this is not a climb to treat like a series of recoverable steps. Even if much of it sits around a moderate average, the accumulated load is the story. Over 36.2 km, small pacing errors compound, especially because the summit sits at 3,135 m. The further you go, the less forgiving the climb becomes if you have been riding above a sustainable effort.

How the gradient unfolds

The available profile points to a long, steady rise rather than a climb defined by repeated descents or major interruptions. The 4.89% average suggests the main character is aerobic pressure, but the 14.31% maximum gradient changes the gearing and pacing equation. You should expect the climb to include sharper ramps that sit well above the average, even if the overall road trends steadily upward.

That contrast matters. A rider who locks into the average gradient mentally can be caught out when the road pitches into double-digit territory. Those steeper moments are where the climb can force spikes above /glossary/ftp, and on a climb this long, those spikes are expensive. The goal is not to flatten every ramp with power. It is to absorb them without turning the second half of the climb into damage control.

Pacing and gearing notes

Start easier than the average gradient tempts you to. Alto de Tochupa rewards patience because the duration is the main difficulty. Settle into a sustainable climbing rhythm early, then protect that rhythm when the road kicks up toward the 14.31% maximum.

A wide climbing gear range is the smart choice. The average gradient does not demand extreme gearing on its own, but the max gradient does. You want a bailout gear that lets you stay seated and keep pressure controlled when the steepest ramps arrive. If you are forced into a low-cadence grind too early, the climb becomes much more costly than its 4.89% average suggests.

The best approach is conservative pacing through the lower and middle sections, with effort held below threshold unless the gradient briefly forces it. If you are still riding smoothly as the road approaches 3,135 m, you can lift the effort late. On a 36.2 km HC ascent with 1,771 m of net gain, the climb is won by resisting the urge to prove anything too early.
