– The high one at Saint-François-Longchamp (T2)

The organisation will give the racers a big plastic bag with their bib number on. In the first transition area, all racers must:
– Put all their swimming and pre-race stuff in this plastic bag.
– Close the bag
– Put this bag in the big case corresponding to his bib number at the exit of the transition area.

The organisation will take those stuff to the finish line, but ONLY the ones with a good conditioner. Racers will be able to have them back after the race nearby the second transition area at Saint-François-Longchamp.
