Tips

Difficulty analysis: This Category 1 climb covers 26.2 km for 858 m of elevation gain, with a moderate average gradient of 3.3%. The difficulty lies mainly in its consistency: from km 0 to 11, the gradient almost never drops below 3% or rises above 5%, with 5% sections at km 6-7 and 8-9. The stretch from km 11 to km 16 gives you a real breather, almost flat, before the road kicks back up in the second half, especially at km 19-20 and 21-22 at 5%.

Tips for managing your effort:

1. Pace yourself from the start: over the first 11 km, the 4% sections come one after another, so you need to stay in your aerobic zone to keep something in reserve.

2. Make the most of the flat spots: use km 11-12 and 15-16, at 0%, to drink, eat, and get your rhythm back before the next ramp.

3. Handle the 5% sections: tackle km 19-20 and 21-22 seated, with a smooth cadence of around 80 to 90 rpm, to save your legs for the summit.
