Col de Méraillet

Col de Méraillet Cycling Climb

The Col de Méraillet sits quietly among the bigger names of the French Alps, but its numbers demand respect. At 10.8 km long with 1,351 m of total ascent and a summit elevation of 1,609 m, this Category 2 climb is no token effort. What makes it genuinely tricky is the gap between its 5.61% average gradient and its 27.6% maximum — a spread that tells you almost everything you need to know about how to ride it.

The Gradient Story

Averages lie on climbs like this. A 5.61% mean across 10.8 km sounds manageable — something a trained rider can sustain at a solid FTP-based pace. But a 27.6% maximum gradient is in a different category entirely. That's a ramp that forces even strong climbers to choose between standing out of the saddle and grinding at near-zero cadence, or spinning a gear so small it risks losing traction.

The math on total ascent reinforces the profile's irregular character. Starting at 1,001 m and climbing 1,351 m to reach the 1,609 m summit means the road gains far more vertical than a clean arithmetic calculation of average gradient over distance would predict — a sign of significant variation in pitch throughout the climb. Expect sections that offer genuine recovery and sections that shut you down fast if you've misjudged effort in the early kilometers.

How the Climb Unfolds

The lower slopes coming off the 1,001 m base tend to lull. When a climb averages 5.61%, the opening kilometers often feel controlled, even conversational. Use that sensation as a trap warning rather than permission to push. Riders who bank too much early on Col de Méraillet pay for it when the gradient spikes.

The extreme upper-range pitches — approaching that 27.6% ceiling — are short but decisive. At gradients above 20%, momentum is essentially gone. You're managing balance and muscular failure simultaneously. Plan for these sections by:

• Dropping cadence deliberately rather than fighting to maintain it
• Shifting earlier than feels necessary — cramming into an easier gear mid-ramp costs more energy than anticipating the pitch
• Staying seated where possible to preserve rear-wheel traction on steep loose-surfaced ramps

Gearing Notes

For a climb with this gradient variance, a compact chainset (50/34 or 46/30) paired with an 11-32 or 11-34 cassette is the practical floor. A 27.6% pitch on a road bike with inadequate gearing is a walk — literally. If you're unsure what gear ratio matches your output to this kind of gradient, use the FTP estimator to benchmark sustainable power before committing to equipment choices.

Riders on gravel bikes with wider-range drivetrains will find the steep pitches more manageable, though the Category 2 designation means total accumulated fatigue across the full 10.8 km is meaningful regardless of what's on your bike.

Pacing Strategy

Treat this as a two-register climb. The moderate sections — which dominate the average — should be ridden at a controlled threshold or just below, preserving glycogen and keeping heart rate from spiking prematurely. The steep ramps are survival efforts: get through them, recover on whatever gradient follows, and reset.

Do not pace the entire climb to the average gradient. That's the central mistake on a route where max gradient is nearly five times the mean. Negative splitting — arriving at the upper third with legs still available — is the target.
