What CCC requires every runner to carry, from the organiser's regulation. The core kit applies to every start. A conditional kit applies only when the organiser activates it, usually from the forecast in the days before the race.

Core kit - always required

17 items, for every start whatever the weather.

  • ID document Passport or ID card
  • Mobile phone Smartphone with the LiveTrail app installed and activated, international roaming on (the course crosses three countries). Keep it switched on and out of airplane mode before, during and after the race. An external battery is strongly advised.
  • Water reserve Sealed, resealable hydration container(s) holding at least 1 L, no plastic bags - 1.5 L recommended
  • Survival blanket At least 1.40 m x 2 m
  • Whistle
  • Waterproof jacket Hooded mountain jacket with a waterproof, breathable membrane (20,000 Schmerber and RET under 13 recommended). The hood must be built in or fixed by the maker's own system, seams sealed, no non-waterproof fabric panels (maker-fitted vents allowed). The race director has the final say at a check.
  • Headlamp x2 Two working head or chest lamps with adjustable output, about 200 lumens recommended. Phones and watches do not count as a light.
  • Spare batteries Backup power for each lamp: a spare set of batteries or battery packs per lamp, or for rechargeable lamps a power bank of at least 5,000 mAh, fully charged at the start, with one lamp always usable while the other charges
  • Race pack Running pack (or other carrier able to hold the timing chip) for the mandatory kit, worn for the whole race. It is tagged at bib pickup and cannot be swapped.
  • Elastic adhesive bandage Self-adhesive elastic bandage for strapping, at least 100 cm x 6 cm
  • Cap or sun hat Cap, bandana or multifunction neck gaiter to protect the head from the sun
  • Waterproof trousers
  • Warm mid-layer Long-sleeved warm second layer, no cotton, at least 180 g in men's size M - or a long-sleeved warm base layer of at least 110 g plus a windproof jacket with DWR treatment (the windproof does not replace the waterproof jacket)
  • Warm hat Beanie, or a multifunction neck gaiter (it can be the same one as the sun protection)
  • Warm gloves Warm and waterproof
  • Personal cup Personal cup of at least 15 cl - bottles and lidded flasks do not count. No disposable cups at aid stations.
  • Food reserve About 800 kcal recommended (for example 2 gels and 2 bars of 65 g)

Conditional kits

Carried only when the organiser activates them. Plan to have them ready in race week.

Additional list (items activated by the organiser) Only if activated

Every runner brings the whole additional list to Chamonix. UTMB activates items one by one from the weather forecast and announces them at least 24 hours before the start; you start with the basic kit plus the items activated. The chart does not say whether the jacket, warm layer and gloves here mean a second one where the basic kit already has one - check the official announcement.

  • Sunglasses One pair can cover both sun and bad weather (e.g. photochromic lenses)
  • Cap or sun hat Saharan-style cap, or any combination that fully covers the head and the back of the neck
  • Sunscreen In its original container, at least 15 ml (SPF 50+ recommended)
  • Long running trousers or leggings Running trousers or long thermal tights (or tights plus socks) covering the whole leg to the ankle, opaque synthetic technical fabric, no cotton, no everyday stockings. They do not replace the waterproof trousers; marshals may stretch the fabric to check.
  • Warm mid-layer Same rule as the basic-kit warm layer: long sleeves, no cotton, 180 g in men's size M, or a 110 g base layer plus a DWR windproof jacket
  • Neck tube or buff A multifunction neck gaiter on top of the one in the basic kit
  • Warm gloves Warm and waterproof
  • Warm mid-layer For example a softshell, down jacket or thick fleece
  • Spare warm clothing
  • Waterproof jacket Same rule as the basic-kit jacket: waterproof, breathable membrane, built-in or maker-fixed hood, sealed seams
  • Protective eyewear Your sunglasses can count if they suit both sun and bad weather (e.g. photochromic lenses)
  • Sturdy trail shoes Closed, sturdy trail running shoes

Questions about the CCC kit

Which kit applies to my race?

UTMB publishes one chart with a column per race. UTMB, CCC and TDS share the full basic kit, and only UTMB adds the forward red light for the Contamines-Montjoie reserve. OCC needs one lamp instead of two and no warm layer, beanie or gloves in its basic kit.

When are the weather items announced?

Every runner must bring the whole additional list to the event. The organiser activates items individually from the forecast and announces them no later than 24 hours before the start; you start with the basic kit plus the activated items.

How is the kit checked, and what happens if something is missing?

Planned and random checks happen during the race, and the kit must be reachable at any time (no sealed bags). Missing safety gear - water, hooded jacket, headlamp, survival blanket or phone - means disqualification; other missing items cost 1 hour on UTMB, CCC and TDS and 30 minutes on OCC. Refusing a check means disqualification.

Do I really need my own cup?

Yes. Aid stations hand out no disposable cups, bowls or cutlery, so a personal cup of at least 15 cl is mandatory and a reusable bowl is recommended for hot meals.
