Are the under 18's properly supervised on training courses abroad?
There is a special trainer in charge of the under 18's abroad.
He is able (at the parents request) to supervise them from the outbound airport to the inbound airport. For example for Australia: take them over at Lyon airport. The young competitors are looked after on the trip, for the time spent in Melbourne and until their arrival at the lodge at Mt Beauty where they join the training programme. There is a similar procedure for the return trip until they are met by their parents at the airport.
