For safety reasons, each athlete must carry all items specified in the mandatory equipment list, even if they are not used, and there will be random equipment checks during the race.

The hot-weather and the cold-weather kits are part of the mandatory equipment. According to the weather conditions, the race organizer might require one of those two additional kits and inform each participant before the opening of the check-in.
