Tips

Difficulty breakdown: This HC climb covers 18.3 km for 1302 m of elevation gain, with an average gradient of 7.1%. The first three kilometres, between 2% and 4%, let you ease into the climb, but the real work starts at km 7 and runs to km 11, where 7 to 8% grades come one after another. The final is the hardest section, with 9% between km 15 and km 16, then 8% up to km 17.

Tips for the effort:

1. Save something in the tank early on. On the first, gentler kilometres, don't go out too hard. Settle into a steady rhythm that will leave you with enough left for the second half.

2. Recover on the respite section from km 12 to km 13. At only 4%, this stretch is ideal for spinning out your legs, drinking and fueling up before the final.

3. Shift to an easier gear for the finale. On the 9% section from km 15 to km 16, keep a smooth, steady cadence. Then use the 5% of the last few kilometres to push the pace back up.
