Difficulty analysis: This HC climb covers 15.8 km and is a demanding test because of its length and high average gradient (7.3%). The difficulty is compounded by recurring steep sections, notably at km 2-3 (9%), 7-8 (8%) and 12-13 (8%), which disrupt your rhythm. The final hectometre (15.0-15.8) at 8% calls for one last significant effort.
Tips for pacing the climb:
1. Managing your pace: Regulate your power output from the bottom to avoid blowing up in the first kilometres at 8-9%. Holding a steady effort, slightly below your threshold, works better than starting too hard.
2. Anticipating gradient changes: Mentally mark the 8% and 9% sections (KM 1-3, 7-8, 12-13). Ease off slightly on the 5-6% parts (KM 6-7, 10-11) to recover without losing time.
3. Saving something for the finish: Keep some in the tank for the last 800 metres at 8%, which are crucial for your final time. Avoid any sudden accelerations in the last 3 kilometres.
