The routes have been published https://www.paris2024.org/en/sport/road-cycling/ and apart from the starts and ends are free to go and see I think. I have teenagers so it seems a good way for them to experience the Olympics.
Overnight bus to Paris, local transport to somewhere to watch, and overnight bus back again?
Seems a reasonable and not too expensive idea to me.
Any thoughts? Advice? I guess time trial would give more to watch. But I don't think it really matters what we do, we watch people whoosh past on bikes and have been to the olympics.
Any I like watching the cycling so a bonus for me.
