Difficulty analysis:
This 25.5 km climb is a long HC-category ascent. Its main difficulty lies in its length and its irregularity. The 3.9% average gradient is deceptive: the profile alternates between very steep sections (several kilometres at 6-7%), recovery stretches (KM 11-15 with gradients of 0% or even downhill) and a demanding finale (KM 20-23 at 6-7%). Pacing is crucial.
Pacing tips:
1. Manage your pace over the long haul: Don't get carried away by the easy early kilometres. Settle into a power or heart rate you can hold for 1h15-1h30.
2. Use the flat sections to recover: KM 12 to 15 (flat and downhill) are a gift. Ease off a little and recover before the hard final section.
3. Prepare for the finale: The KM 20 to KM 23 section (6-7%) is the steepest. Save something for the "wall" and control your effort so you don't blow up.
