Tour de France 2022 route has just been announced.
And first pre-pre-registrations for l'Etape has been already opened too - initial 100 thanks to TdF Club (which I took advantage of, and have already registered), then another 400 from Škoda, with official ones opening next Monday 18th Oct at 16h.
The route essentially seems to be La Marmotte in reverse, just a little bit shorter/easier.
