- Alpine weather changes fast above 2000m — expect cold, rain, or snow even in August despite mild valley temps.
- Strict intermediate cutoffs at each major checkpoint; missing one ends your race regardless of finish potential.
- Drop bags allowed only at specified life bases (e.g. Courmayeur for UTMB) — plan kit swaps accordingly.
