The Ultra Trail du Mont-Blanc

The Ultra-Trail du Mont-Blanc, more commonly known as UTMB, is a trail race that takes place every year in Chamonix Mont-Blanc. Considered one of the most complicated races in its field, it is a must for trail runners from all over the world.

The UTMB, the meeting place for the trail elite

In the world of trail running, the UTMB is the ultimate competition, the one that all trail runners dream of taking part in one day. Created in 2003, it offers participants the chance to complete the tour of Mont Blanc as quickly as possible. This world-renowned event crosses three countries: France, Italy and Switzerland.

Each year, solidarity race numbers are available. They are intended for runners wishing to support one of the partner associations with a minimum donation of €2,000. Trailers choosing this option do not need to go through the draw to start the UTMB.

Practical information about the event

Before setting off on the UTMB or even registering for it, there are some practical information you should know. Indeed, these races should not be taken lightly and require a very good physical condition.

The necessary equipment

As we know, the weather can be capricious in the mountains. It can be even more so in the Mont Blanc massif, where it can be over 30°C but also -10°C at an altitude of over 2,000 metres. In order to guarantee the safety of the runners, specific equipment is mandatory. You will find in particular in the basic kit :

  • A bag to carry the equipment during the race
  • A mobile phone with the Liverun application
  • An ecocup of 15 cl at least
  • At least 1L of water in reserve
  • 2 working lamps, with batteries or spare battery
  • A survival blanket
  • A whistle
  • An adhesive elastic band
  • A food reserve
  • A jacket with a hood
  • Sticky trousers
  • Bandana, Buff or cap
  • A second layer of clothing
  • A hat
  • Gloves
  • Waterproof overtrousers
  • An identity card

Vaseline, a GPS watch, a sewing kit and some cash are also recommended to cover any unforeseen circumstances. Depending on the weather conditions, trailers may be asked to bring a heat wave kit or a bad weather kit.

Safety on the race

Before starting the race and in order to validate his registration, a runner must submit a medical certificate. During the races, participants are responsible for their own safety. It is up to them to know how to assess themselves and to take care of their health. Of course, solidarity also has its place in the competition.

Note also that the organisation does everything possible to ensure the safety and medical care of the runners. Since 2007, a medical commission meets at the end of the UTMB to review the medical activity during the race.
