Difficulty breakdown: The Yizu La is an HC climb: 15.4 km at an average gradient of 6.5% for 1005 m of elevation gain, so it's a serious test of endurance. The gradient stays punchy over most of the route, between 4% and 7% depending on the section, with only one real respite between km 8 and 10. The steepest parts come between km 5 and 6 (7%), then between km 7 and 8, 11 and 12, and 13 and 14 (6%), which keep breaking your rhythm.

Pacing tips:
1. Start controlled In the first few kilometres, on 4% to 5%, hold a steady effort so you reach the 7% ramp between km 5 and 6 with plenty left in the tank.
2. Make the most of the km 8 to 10 reprieve Use those two kilometres at 2% to recover, drink and eat, without going hard for no reason.
3. Handle the km 11 to 14 kickers Take the 6% sections with a smooth, light cadence and a gear you can spin comfortably, then save your last reserves for the 3% finish between km 14 and 15.4.
