Difficulty analysis: At 3348m of elevation gain over 77.6km, this HC climb is extremely long, but its average gradient of 4% is moderate. The difficulty lies in the cumulative effort and the big changes in gradient, notably several sections at 7-9% (KM 32-33, 65-67, 70) and steep descents (KM 34-38 at -7%).
Pacing advice:
1. Ride within yourself from the start to save energy for the long haul, especially on the first kilometres, which are less steep.
2. Anticipate the gradient changes: ease off before the steep sections (≥7%) and use the descents to recover actively, spinning your legs.
3. Break the climb down into chunks, focusing on the hard stretches (late KM 60-77 with sustained gradients).
