Odyssée 100K

The aid stations and their locations are shown in the course profile above. During the race, two types of aid stations will be available: liquid and solid. The products offered will vary depending on the type and location of the station. The detailed list of items available at the 2026 aid stations will be updated in the coming weeks and published under this section.

Crew access is authorized for the 100K category runners under the following conditions:

1. Authorized Locations

• Crews are permitted only at designated aid stations (Base Nord).
• Assistance is allowed only:
  • Upon presentation of an "Assistance" ticket.
  • With the approval of the aid station team leader.

2. Assistance Conditions

• Assistance may be provided by only one person using a single 30-litre bag, issued by the organization at check-in.
• Only members of the official event medical team are authorized to provide medical or paramedical care. Assistance from professional teams or individuals (medical, paramedical, or otherwise), even if they are family members, is strictly prohibited.
• Crews may provide food, drinks, and gear only.

3. Pacers

• Pacers are not authorized in any race.

The mandatory gear for this race (100K category) is detailed HERE.

At the race-pack collection, each participant will receive one 30-liter bag. After filling the bag with the items of their choice, labelling it and closing it, runners can drop them off at the start. For logistics reasons, UTMB World Series events only accept the official drop bags that are distributed during the check-In. These bags are reusable, so we ask the runners who have already received one to reuse it each time they take part in a UTMB World Series event. Poles are not allowed in drop bags.

Drop bags will be accessible twice along the race track, both times at the Base Nord Aid Station.

For more information regarding drop bag logistics, consult the full race regulations HERE.

Participants must be at least 18 years of age on the date of the race to enter.

Finishing this race will give you 3 Running Stones. Your Running Stones will be automatically logged in your UTMB account.
