Difficulty breakdown: This 38.8 km climb has a three-act profile. The first section (KM 0-22) is moderate, with gradients generally between 2% and 5%. The difficulty ramps up from KM 22 (6%) and becomes serious over the last 10 km, with a steep stretch at 9% to 13% between KM 30 and 34, followed by a short descent before a brutal finish (14% over the last 800 meters).
Pacing advice:
1. Ride endurance pace over the first half: The first 20 km (average gradient ~3%) give you time to settle in without blowing your heart rate. Use this section to find a steady rhythm and save your legs.
2. Prepare for the final wall: The KM 30-34 section (9%-13%) and the last kilometer (14%) are where the race is decided. Managing your pace before this part (KM 22-29) is crucial so you hit the steepest pitches with something left in the tank.
3. Make the most of the breather: The slight descent between KM 34 and 36 (-2% to -6%) is a rare chance to recover actively. Ease off a little so you tackle the last steep ramp (KM 36-38.8) with fresh legs.
