Colle di Buggiano

Overview

Colle di Buggiano is a short, honest climb that packs its work into a tight window. Over 2.3 km the road lifts you from a start elevation of 35 m to a summit of 184 m, delivering 149 m of net elevation gain. The average gradient sits at 6.46%, with the steepest ramp touching 9.19%. That earns it a category-4 rating — the gentlest of the classified tiers, sitting below categories 3, 2, 1 and the hors catégorie monsters — but do not mistake "category 4" for "easy." At this length, 6.46% is a climb you can attack, and the temptation to overcook the effort is real.

How the Gradient Unfolds

The shape here is compact and consistent rather than dramatic. With a 6.46% average across just 2.3 km, the climb never lets you fully recover, but neither does it bury you in an unrelenting wall. The gap between the 6.46% average and the 9.19% maximum is modest — about 2.73 percentage points — which tells you the hardest ramp is a firm step up from the norm, not a shock. Expect a steady grind broken by a stiffer pitch where the road tilts toward that 9.19% figure. Interestingly, the net gain of 149 m exceeds the total ascent figure of 131 m, a sign the profile trends upward cleanly without meaningful dips or false flats to break your rhythm.

Pacing Notes

Short climbs reward precision. Because the whole effort fits inside 2.3 km, your pacing target should hover around — or slightly above — your threshold. If you know your FTP, aim to ride this at or just over it, holding back only a touch for the 9.19% ramp so you do not blow apart before the summit at 184 m. Not sure where your threshold sits? Run the numbers through the FTP estimator before you plan the effort. The key is to arrive at the steepest section with something in reserve, then use the final metres of the 149 m gain to empty the tank rather than pacing evenly the whole way.

Gearing

For a 2.3 km climb averaging 6.46% and peaking at 9.19%, most riders will be comfortable on a compact setup. A 34×32 will cover the bulk of the climb and keep your cadence healthy through the steady 6.46% sections. If you carry fatigue, ride at a lower power-to-weight, or simply prefer to spin, a 34×34 gives you extra insurance for the 9.19% ramp without forcing you out of the saddle. Either way, err toward the easier cog — protecting your cadence over such a short distance costs you nothing and keeps the effort repeatable.

Summary

Colle di Buggiano is a sharp, satisfying test: short enough to attack, steep enough to sting. Ride it at threshold, respect the 9.19% pitch, and let the summit come to you.
