Col de la Givrine

Overview

Col de la Givrine is a Category 3 climb in Switzerland, running 12 km from a start elevation of 835 m to a summit at 1233 m. The net elevation gain across those 12 km is 398 m, which puts the climb firmly in the moderate bracket on paper. It is the kind of ascent that rewards steady legs rather than raw explosiveness, and the numbers alone do not tell the whole story.

The gap between the net elevation gain and the total ascent is where this climb reveals its character. You gain 398 m net, but you actually climb 948 m in total — a 550 m difference that gets given back as descent along the way. That undulation means you are repeatedly climbing and giving up altitude, so the effort is punchier and more fragmented than a single 398 m grind would suggest. Expect to work harder than the average gradient implies.

How the Gradient Unfolds

The average gradient of 3.31% is deceptive. On a rolling profile like this, the mean is dragged down by the descending and flat sections, masking pitches that bite well above it. The steepest ramp reaches 16.41%, so the demand is spiky rather than uniform.

• Flatter and recovery sections where the road descends or levels, dropping the effort
• Repeated short climbs that force you to re-accelerate after each dip
• A steepest ramp at 16.41% that demands a hard, brief surge

Pacing Notes

On a smooth, consistent climb you can hold an even effort and let speed take care of itself. This climb's undulation breaks that logic. Chasing an even speed here will spike your power on every short ramp and waste it on the descents. Instead, hold an even effort anchored to your sustainable power output: ease slightly over the crests, recover on the drops, and avoid burning matches on the 16.41% ramp. If you do not know your ceiling, run the FTP estimator first so your target is grounded in real numbers.

Gearing

Gearing is governed by the steepest gradient, not the average. A 16.41% ramp is enough to stall a rider carrying too tall a bottom gear, so plan around it. Fit a compact or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you the low end to spin the steep pitch without grinding. Check your setup before the ride; the flatter average tempts riders to under-gear.

Summary

• Length: 12 km
• Average gradient: 3.31%
• Maximum gradient: 16.41%
• Net elevation gain: 398 m
• Total ascent: 948 m
• Category: 3

Col de la Givrine is not a climb you conquer by threshold alone. The modest net gain hides 948 m of total climbing across a rolling profile, so pace to effort, gear for the steep ramp, and treat every crest as a cue to ease rather than push.
