RUNNING STUFFSince the bike course isn’t a loop, this triathlon has the particularity of having two transition areas:
– The low one at Saint-Rémy-de-Maurienne (T1)
– The high one at Saint-François-Longchamp (T2)

For Distance L-3400, running gear is OBLIGATORY to be deposited in the high bike park at T2 on Friday between 3:00 pm and 7:30 pm. Depending on the weather, remember to protect them from rain and dew for the night to avoid finding your personal belongings wet.
SWIMMING STUFFThe 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.
PICKING UP YOUR CYCLING STUFFYou will be able to pick up your bike gear left in the “TOP” bike park in the T2 transition area from the moment the last runner finishes the bike race (~4:30 pm) until 7:15 pm.
