Difficulty analysis:
At 19.2 km, this climb is a true test, rated HC (beyond category). The difficulty lies in its length and the succession of demanding gradients. The first third (0-6 km) is a progressive warm-up (2% to 6%), but the gradient settles above 5% from the 4th km onwards. The hardest sections, at 7%, come at km 6-7, 10-11, 12-13 and especially 16-17, the latter being particularly steep (76 m of climbing) before the finish.
Tips for managing your effort:
1. Pacing: Resist the urge to go out too hard over the first few flatter kilometres. Settle into a steady rhythm you can hold on 6-7% gradients, so you don't blow up before the critical sections.
2. Anticipate the changes in gradient: The re-attacks after the short breathers (KM 11-12 and 17-18 at 4%) are key. Save something in the tank for the final 7% ramps after these more rolling sections.
3. Focus on the finale: The last kilometre (KM 18-19) at 5% is tough, but the final downslope (-2% over 200 m) gives you a chance to accelerate for the line. Keep pushing until the "19.0" marker.
