Alto de los Gavilanes cycling climb profile
Alto de los Gavilanes is a long Colombian category 1 climb that asks for discipline more than aggression. On paper, 19.5 km at 6.21 percent is not brutally steep in isolation, but the real difficulty is how long that pressure lasts. The climb rises from 2155 m to 3364 m, gaining 1209 m from bottom to summit, so the effort is sustained enough that early pacing mistakes will compound.
The key number is the gap between the average gradient and the maximum gradient. A 6.21 percent average tells you the climb is mostly an aerobic grind, but the 11.2 percent maximum means there are sharper sections that can force a change in cadence and torque. The available profile data does not identify exactly where those steepest pitches arrive, which matters tactically: you should ride the climb as if the hard sections can come at any point, rather than spending energy early because the opening feels manageable.
How the gradient rides
From bottom to summit, the defining feature is the climb's duration. At 19.5 km, Alto de los Gavilanes sits in the zone where a rider cannot fake the effort with short surges. Even if much of the road tracks near the average, the accumulated load of climbing for that distance means small over-threshold efforts become expensive.
The 11.2 percent maximum is the warning label. On a climb with this length, a double-digit ramp is not just a momentary inconvenience. If you hit it over-geared or already above your sustainable effort, it can push you into a metabolic debt that takes several minutes to repay. That is why this climb rewards riders who keep the early effort controlled, stay seated when possible, and treat the steeper ramps as cadence-management problems rather than attacks on the road.
Pacing strategy
Use the average gradient as your anchor, not your target for every meter. The climb averages 6.21 percent across nearly 20 km, so a steady effort around sustainable climbing power is the safest approach. If you pace by FTP, the goal should be to avoid repeated spikes above threshold unless you are close enough to the summit to absorb the cost.
A practical pacing shape:
- Start slightly under control while the climb settles in.
- Hold a steady aerobic rhythm through the main body of the ascent.
- On ramps approaching the 11.2 percent maximum, let speed fall before forcing power too high.
- Save any real acceleration for the final portion, when the remaining distance is no longer the main risk.
If you do not have a recent benchmark, estimate your sustainable range before riding it with an FTP estimator. This is the kind of climb where knowing the ceiling matters more than knowing your best short effort.
Gearing notes
Bring gearing that lets you stay seated and keep cadence under control on double-digit gradients. The average is moderate enough that a standard climbing rhythm will work for long stretches, but the maximum gradient of 11.2 percent makes a low gear valuable. If your easiest gear only feels comfortable on steady 6 percent roads, it may leave you grinding when the road kicks up.
The smart setup is one that gives you room to absorb the steepest sections without turning the climb into a series of strength efforts. On Alto de los Gavilanes, the rider who protects cadence and keeps the effort even is likely to arrive at 3364 m in far better shape than the rider who treats the early average gradient as permission to press.
