Difficulty breakdown: At 47.5 km, this climb is demanding because of its length, but its moderate average gradient of 3.6% makes it manageable over the distance. The real challenge is how it's broken up: sharp kicks (sections at 14% at km 16 and 28, and 9% at km 27) are interspersed with flat stretches and short descents (km 17, 18, 30, 40, 47), which disrupt your rhythm.
Pacing tips:
1. Settle into a steady rhythm: Resist the urge to go too hard in the first few kilometres, which are very flat. Save something in the tank for the three main walls (km 16-17 and km 27-29).
2. Use the descents to recover: The downhill sections (like km 30 at -24%) are crucial. Ease off, drink up and refuel without pushing it.
3. Anticipate the gradient changes: The finish is uneven (km 45 at 8%) before a final descent. Adjust your gearing accordingly to keep a steady cadence all the way to the top.
