We would be grateful if you would refrain from using these private passageways, so as to ensure the continuity of our routes and agreements.

On the day of the event, always follow the course markers, not your watch.

• Distance : 25 km
• Departure: Les Rousses at 8:00 a.m.
• Arrival : Les Rousses
• Ascent: 1260 m D+ (gradient)

Numbers can be collected at the trail show in Les ROUSSES .

Friday, June 5: 2 to 8 p.m.

Saturday, June 6: 11 a.m. to 7 p.m.

You can also pick up your race numbers on Sunday June 7 at the start of your race 1h30 beforehand.

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. 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).
