each participant🔴 must carry with them all the items listed in the mandatory equipment checklist 🔴

UTMB implies the following rules:

1. Runners must always carry with them all items of the mandatory gear checklist (see paragraph EQUIPMENT). They have to carry their equipment in a pack, tagged during race-pack collection, which cannot be changed along the race route. At any moment of the race, the race directors might verify the pack and its contents. The runner must accept these checks or they might be excluded from the race.
2. Aid stations supply drinks and food to be consumed on site. The organization only supplies still water or energizing drinks for filling water bottles or hydration packs. Runners should make sure that they have, when leaving each aid station, the necessary drinks and food to keep them going until the following aid station.
   For slower runners, the longest sections without any aid stations can last more than 4hrs during the UTMB®, more than 3hrs during the  CCC® and OCC and more than  6hrs during the TDS®.
3. During the UTMB®, CCC® and TDS®, personal assistants are only allowed at some aid stations (*). Assistants may only enter the area specifically designated for them and must comply with all instructions of aid station team leader and staff. Runners may only have one assistant, without specific equipment other than a bag with a maximum volume of 30 liters. Assistance given by a team of professionals, or any medic or paramedic, is strictly forbidden. A part from this area, the rest of the aid station is strictly reserved for runners.
   No assistance is allowed, at any point along the race route, during the OCC, MCC and YCC.
4. Runners may only be accompanied in the areas where assistance is allowed - these areas are clearly marked in the proximity of the aid station. It is forbidden to accompany or be accompanied along any part of the race route by someone who is not registered for the race. 

EQUIPMENT

In order to ensure their security and the smooth running of the each event, each participant must carry with them all the items listed in the mandatory equipment checklist (see below).
The “heat-wave”, “winter” and “bad weather” kits are part of the mandatory equipment. According to the weather conditions, the organization might require one of those three additional kits and inform each participant before the opening of the race-pack collection. Each participant must therefore present their mandatory equipment - including the additional kit requested by the organization - in order to get their race-bib, and agree to keep it with them throughout the event.

Please note: the items included in the mandatory equipment checklist are the basic pieces which each trail-runner must adapt according to their own skills. In particular, you should not choose the lightest possible clothing but prefer clothing that really provides good protection in the mountains against cold, wind and snow, and therefore better safety and performance.
