Tips

Difficulty breakdown: This HC climb covers 8.5 km with 497 m of elevation gain, at an average gradient of 5.8%. The start is easier, with a near-flat section at 1% over km 1.0-1.5, but the real difficulty kicks in between km 5.0-5.5 (7%) and km 6.0-7.0 (6%). The finale is the toughest: 7% over km 7.5-8.0, then 9% over km 8.0-8.5.

Tips for pacing your effort:

1. Save your legs from the start. Don't go out too hard over km 0.0-0.5 at 3%, because most of the real work happens in the second half of the climb.

2. Recover on the flat bits. Use the 1% section at km 1.0-1.5 to spin your legs out, eat and drink, and settle back into your rhythm before the steeper sections.

3. Hold a steady cadence in the final. At 9% over km 8.0-8.5, shift into an easier gear, stay seated, and keep a smooth, consistent cadence all the way to the summit.
