Col du Goleron

Overview

The Col du Goleron is a genuine mountain effort: 11 km of continuous climbing that lifts you from a start elevation of 500 m to a summit at 1367 m. That is a net gain of 867 m over the ride, packed into a road that never really lets you settle. With an average gradient of 7.85% and a Category 1 rating, this is a climb that rewards patience and punishes anyone who goes out too hard. It sits just one rung below hors catégorie, and it earns the label honestly.

How the Gradient Unfolds

An average of 7.85% tells only part of the story. The headline number here is the 21.79% maximum gradient — a wall steep enough to break rhythm and force you out of the saddle whether you planned to stand or not. Because the average is high but the max is dramatically higher, you can expect the road to pulse: long stretches hovering near the average, interrupted by pitches that spike well into the teens and beyond. The gap between the 867 m net gain and the 802 m total ascent is small, which tells you the climb is relentlessly uphill with little to no respite — no long false-flats or descents to recover on. Treat every ramp as if the next one is steeper, because on Goleron it often is.

Pacing Notes

The single most useful thing you can do on an 11 km climb this steep is hold a steady effort. Anchor your pacing to your FTP and aim to ride the bulk of the climb just below threshold, leaving a reserve for the 21.79% max pitch that will spike your power whether you like it or not. If you do not know your current threshold, run the numbers through the FTP estimator before you attempt this one — going in blind on a Category 1 climb with an 867 m gain is how riders blow up in the first few kilometres. Save your matches for the steep ramps and let the average-gradient sections tick by.

Gearing

Do not under-gear this climb. With sustained pitches around 7.85% and a maximum touching 21.79%, you want a compact chainring and a wide-range cassette. A 34×32 is the sensible floor for most fit riders, giving you a bail-out low enough to keep cadence on the average slopes. For the steepest ramps — and for anyone climbing at a lower FTP or on tired legs — a 34×34 is the smarter choice, buying you the extra torque to spin over the 21.79% wall instead of grinding to a standstill. On a climb with 802 m of total ascent, protecting your knees and your cadence pays off long before the summit.

Summary

The Col du Goleron is a complete Category 1 climb: long enough to test endurance, steep enough to test power, and topped by a summit that sits nearly 900 m above where you started. Pace it to your threshold, gear it generously, and respect the 21.79% pitch.
