Quad damage

Quad damage risk is high (index 54 of 100), with 51% of the load in the first half: 2 critical descents, the last of them run on already damaged legs. Downhill-specific preparation and a controlled early pace pay off here.

• Control on the marked descents until km 48, target pace until km 77, free after that. Short descents not listed: target pace.
• #1 · 10.1–22.2 km · 1248 m D−, -10.3% · 77% of the race ahead → control
• #2 · 26.3–28.2 km · 280 m D−, -15.3% · 71% of the race ahead → control
• 80.6–93.0 km · 1351 m D−, -10.9% · 3% of the race ahead → even, first half under control, let go at the end
