Puerto de las Palomas cycling climb profile
Puerto de las Palomas is not long, but the numbers explain why it rides like a serious climb. At 4.3 km with an average gradient of 10.56%, it gives very little room to hide. The climb starts at 1213 m and reaches 1662 m, gaining 449 m from bottom to summit, which means the difficulty is concentrated rather than spread out.
That combination matters. A rider can often bluff through a short climb if the average gradient is moderate, but an average above 10% changes the pacing problem. You are not managing momentum as much as managing torque. Cadence drops quickly if the gear is too big, and once the road pitches toward the maximum gradient of 19.15%, any early over-pacing becomes expensive.
How the gradient shapes the ride
The defining feature is density. Puerto de las Palomas compresses a category 1 effort into 4.3 km, so the climb rewards riders who can settle into threshold power without drifting into repeated surges. The average gradient tells you the road is persistently steep, while the 19.15% maximum suggests at least one section where seated rhythm may break down and low-speed control becomes part of the effort.
The start elevation of 1213 m also changes the feel of the opening kilometres. You are already climbing from a relatively elevated base, then finishing at 1662 m. The key is not to treat the lower slopes as a warm-up. With only 4.3 km to work with, the climb can feel tempting to attack early, but the gradient is severe enough that going too hard before the steepest pitch risks turning the final section into damage limitation.
Pacing and gearing notes
Ride this as a controlled, high-resistance effort rather than a climb where you chase speed. The best pacing strategy is to start just under your sustainable climbing intensity, keep pressure smooth through the middle, then lift only once the worst gradients are behind you or the summit is clearly within reach.
A low climbing gear is the practical choice here. The average of 10.56% means you should expect to spend most of the climb in your easiest ratios, not just save them for the maximum ramp. If you are riding to power, anchor the effort around your /glossary/ftp rather than responding to every change in gradient. On the 19.15% section, protect cadence first. Standing can help keep the bike moving, but repeated accelerations will cost more than they give back.
Puerto de las Palomas is short enough to invite aggression, but steep enough to punish it. The fastest ride will usually come from restraint in the first half, clean gearing through the steepest ramps, and a final push once the climb stops asking for survival torque.
