We advise you to come well in advance for the collection of the numbers in order to be sure to take the start.

You must bring the following documents with you:

  • Your official, valid identification document
  • 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.

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).
