Race bibs can be picked up at the Omnibus Hall in Les Rousses.
Friday, June 4: 2:00 p.m. to 8:00 p.m.
Saturday, June 5: starting at 6:30 a.m.
You must bring the following documents with you:

- Proof of registration
- Your license or medical certificate if not validated beforehand
The number will be accompanied by a timing chip. Participants must take care not to damage it. To do so, the number must be fixed without being folded on the chest or the belly and remain visible throughout the race. In case of damage to the number or the chip, preventing its detection, the participant will not be able to make a claim. The organizer will not be held responsible.
Another person may pick up the race bib, provided they present the same documents required for in-person pickup: the participant’s ID (photo ID accepted), proof of registration (PPS or medical certificate if not validated).
For the 25K race, starting corridors have been set up to ensure a smooth and enjoyable running experience for everyone.
- The starting groups are determined based on the estimated finish time provided during registration and theITRA Index.
- The SAS number is printed on the race bib and can be found in the registration packet once the bibs have been assigned.
