Looks like I'm going to be visiting France next year and the timing will be right to attend the Tour de l'Avenir. I've decided to hire a campervan and follow the race, but am having some difficulty finding information about it. Does anyone know (or know how to find out) how the spectator numbers compare to the Tour de France? The Tour de l'Avenir goes over some of the same cols as the TdF, but I'd rather not park on them days in advance if it's not necessary.
All info gratefully received.
