Mandatory Gear for the UTMB: The Complete List
Publié le 12 juillet 2026
Mandatory gear must be carried from start to finish, under penalty — race marshals can check it at any time. Here is the list with the exact numeric specifications.
À retenir
- Waterproof jacket: 10,000 Schmerber minimum required (20,000 recommended), RET < 13
- 2 headlamps each with a backup power source, 200 lumens recommended
- Survival blanket: 1.40 m × 2 m minimum
- Water reserve: 1 L minimum, 1.5 L recommended on the UTMB/TDS/CCC
Why these precise requirements?
Each specification addresses an identified high-mountain risk: hypothermia in prolonged bad weather (jacket, warm layer, survival blanket), night navigation on a course partly run after dark (headlamps), dehydration on long stretches without aid stations (water reserve). These are not arbitrary constraints: the rules are adjusted after each edition based on incidents observed on the course.

FAQ
What is the minimum waterproofing for the mandatory UTMB jacket?
10,000 Schmerber minimum required, with a recommended RET under 13, sealed seams and an integrated hood. In practice, most runners aim for 20,000 Schmerber for reliable protection in degraded high-mountain conditions.
How many headlamps are mandatory at the UTMB?
Two, each with its own backup power source. 200 lumens are recommended. For a rechargeable lamp, an external battery of at least 5,000 mAh is advised to cover the distance.
What is the minimum amount of water you must carry at the UTMB?
1 liter minimum in sealed, resealable containers, 1.5 liters recommended on the UTMB, the TDS and the CCC given the distance between aid stations.
What are the minimum dimensions of the mandatory survival blanket?
1.40 m × 2 m minimum. This is systematically checked by race marshals, as is the self-adhesive elastic bandage (100 cm × 6 cm minimum).
Is the mandatory gear the same for all UTMB races?
The base is the same (waterproof jacket, warm layer, survival blanket, headlamps, water reserve), but the recommended water quantities and some items vary by race distance — check the official list for your specific race before the start.
