Coll del Canadell

Overview

The Coll del Canadell is a category 3 climb that runs 7.4 km from a low start elevation of just 12 m up to a summit of 350 m. On paper the average gradient of 4.54% reads as friendly, rolling terrain — the kind of number that suggests a steady tempo effort rather than a suffer-fest. But averages flatten out the story. The net elevation gain of 338 m is spread unevenly across the climb, and a maximum gradient of 17.24% lurks somewhere in the profile to remind you that this is not a uniform ramp.

With a total ascent of 290 m recorded against a net gain of 338 m, the climb is essentially a one-way haul upward: there is little descending or false-flat give-back to recover on. Everything you climb, you keep.

How the Gradient Unfolds

The gap between the 4.54% average and the 17.24% maximum is the defining feature here. A climb that averages under 5% but spikes past 17% is a climb of two personalities: long stretches of gentle-to-moderate gradient bookending one or more short, sharp walls. Expect sections that sit comfortably below the average, where you can turn a big gear and hold rhythm, punctuated by a pitch that forces you out of the saddle or deep into your easiest cogs.

Over 7.4 km, gaining 338 m net, the sustainable portions do most of the work in terms of distance while the steep ramp does most of the damage to your legs. Ride the flatter kilometres too hard and you will arrive at the 17.24% wall already in the red.

Pacing Notes

Because the hard part is concentrated rather than sustained, pacing is about restraint on the easy sections. Hold your effort to a level you can lift when the road kicks — a target near or just below your FTP works well for a 7.4 km climb of this length, leaving a reserve for the steep pitch.

If you are unsure what your threshold actually is, run the numbers through the FTP estimator before you commit to a plan. Knowing your FTP turns the 17.24% ramp from a guess into a calculated surge: you simply spend a little above threshold for the short time the wall lasts, then settle back to tempo for the remaining gentler gradient up to 350 m.

Gearing

For a climb that averages 4.54% but bites at 17.24%, gearing choice is dictated by the wall, not the average. A compact 34-tooth inner chainring paired with a wide-range cassette is the sensible baseline. A 34×32 will get most fit riders over the steep pitch while keeping a workable cadence on the moderate slopes. If you weigh more, ride at a lower cadence, or simply prefer to spin, step up to a 34×34 — that extra sprocket is cheap insurance against grinding to a standstill on the 17.24% ramp. On the long stretches below the 4.54% average you will barely touch these low gears, so err toward the easier setup.

Summary

Coll del Canadell rewards a patient, front-loaded-with-restraint approach: 7.4 km is short enough to push, but the spike to 17.24% punishes anyone who spends too freely on the way up to 350 m. Pace to your threshold, gear for the wall, and the 338 m of net climbing goes by cleanly.
