What you should know
- UTMB races enforce a mandatory gear list; kit checks happen at bib pickup and randomly on course.
- Cols exceed 2,500m on longer routes, so expect freezing temps, wind, and possible snow even in late August.
- Each race has strict intermediate time barriers; miss one and you are pulled from the course.
- Drop-bag access is limited to specific bases (e.g., Courmayeur on UTMB); check your race's rules before packing.
- Long technical descents on rocky, wet trails reward poles and conservative pacing early to save your quads.
