Equipment advice

Prepare and test your equipment

The choice of suitable equipment is a key factor in the success of your race. Ultra-endurance requires thorough preparation, including the choice of the equipment that you take with you.

The month of August in the Mont-Blanc area can be very hot (more than 30°C), but it can also be very cold (up to -10°C experienced above 2000m), with rain, hail or even snow. Your equipment must be suitable for confronting all types of conditions and enable you to spend one or two nights on the race route, according to the speed of your progression. In the case of an incident, your equipment must enable you to await help in sufficiently safe conditions.

The UTMB® imposes obligatory equipment which all runners must have with them permanently to avoid risk of penalty. Checks are carried out during the races. We can only encourage runners to also take with them the equipment which is highly recommended, as well as the equipment that we advise them to have.It is essential to be able to adapt your equipment to your reality, test it during training sessions in varying conditions and take everything that will be useful and necessary. Weight is a concern, but don't be too minimalist. Optimise your chances of success and your performance through judicious choice.

Le matériel obligatoire UTMB® par UltraTrailMontBlanc

In order to ensure their security and the good progress of the each event, each participant must have at their disposal the all the obligatory equipment on the list, detailed below.
The  “heat-wave”, “winter” and “bad weather” kits are integrally a part of the obligatory equipment. According to the weather conditions, the organisers can activate a kit and inform each participant before the opening of the race-bib distribution for their race. Each participant must therefore present their obligatory equipment, including the kit activated by the organisers, in order to  retrieve  their race-bib, and agree to keep it with them throughout the event.

It is important to note that the material imposed by the organisers is a vital minimum which each trail-runner must adapt in function to their own capacities.  In particular, they must not chose the lightest weight clothing possible in order to gain a few grammes, but opt for clothing which really offers good protection in the mountains against the cold, wind and snow, which therefore give better security and a better performance.
