Puerto San Gamello cycling climb profile
Puerto San Gamello is a short, contained climbing effort rather than a long mountain pass. At 4.6 km with an average gradient of 6.2 percent, it sits in the awkward middle ground where the climb is not long enough to force pure survival pacing, but it is steep enough that riding above threshold too early will come back quickly.
The road rises from 374 m to 658 m, gaining 284 m from bottom to summit. That tells you the main demand clearly: this is a sustained aerobic climb with limited room to hide. The category 3 label fits the shape of the effort - serious enough to split a group, not so long that the best strategy is simply to settle and wait.
How the gradient unfolds
The available profile data gives the climb as 4.6 km at 6.2 percent, with a maximum gradient of 9.78 percent. There is no reliable segment-by-segment breakdown here, so the important takeaway is not where the steepest section comes, but how to prepare for it.
A 6.2 percent average over this distance usually feels manageable if ridden evenly, but the 9.78 percent maximum changes the pacing equation. Even if the steepest pitch is short, it is close enough to double digits that it can force a torque-heavy effort, especially if you arrive already above your sustainable climbing power. The climb should be treated as mostly steady, with at least one sharper ramp that can expose poor gear choice or impatient pacing.
Pacing and gearing notes
The right approach is to start slightly controlled, not passive. On a climb this short, giving away too much time or speed at the bottom is unnecessary, but the average gradient is high enough that a hard opening kilometre can push you into a debt you will not fully clear before the summit.
Use the opening minutes to lock into a sustainable rhythm around your climbing threshold rather than chasing every acceleration. If riding by power, this is the kind of climb where /glossary/ftp discipline matters: small surges over FTP on the steeper pitch can be fine, but only if they are planned and brief.
Gearing should account for the 9.78 percent maximum, not just the 6.2 percent average. A setup that feels comfortable at tempo on the main gradient may become too heavy when the road kicks up. Choose a low gear that lets cadence stay under control on the steepest ramp without forcing a standing grind.
Riding it well
Puerto San Gamello rewards riders who keep pressure on the pedals without turning the lower slopes into a time trial from the first metre. Think of it as a compact threshold climb with a sting: ride the average, respect the maximum, and save enough to lift the pace over the final part rather than simply defend it.
