“Sur” in the sentence “Bienvenue sur le Tour de France”
Bonjour! Pourquois qu’on dit <sur> dans cette phrase en place de <à>? I am watching the Tour de France and this was written on some of the coverage - I cannot sort out why “sur” here because I’ve not seen that before as a Canadian Anglo with some francophone roots (clearly not great at French but try to keep up the little I have and trying to grow it). I appreciate your help!
