Difficulty breakdown: At 10.7 km, with 727 m of elevation gain and an average gradient of 6.8%, this climb is rated HC (beyond category) and ranks among the toughest out there. The real crux is the central section: between km 1.0 and km 7.0, the gradient bounces between 9% and 11% with no real respite. The opening at 6% (km 0.0-1.0) lets you settle in, but then you have to hold a sustained effort for six kilometres. The 2% stretch between km 7.0 and km 8.0 gives only a brief recovery before the finale.
Pacing tips:
1. Ease into it. On the first kilometre at 6%, stay in your aerobic zone so you reach km 1.0 with enough left in the tank to attack the 10% block.
2. Be steady through the central block. Between km 1.0 and km 7.0, pick a gear that lets you hold a smooth cadence, and don't keep shifting every time the gradient jumps between 9% and 11%.
3. Don't let off the pressure. On the false-flat downhill from km 8.0 to km 10.0 (-1%), keep pedalling to hold your momentum, and save something for the final 700 metres at 5%.
