I just checked the Peacock app….in the “Live & Upcoming” section, if you scroll forward, it has the TdF Stage 1 and lists the time as 5hrs 30min, so it should be the whole stage.
Have to admit, I am actually pretty pleased with the change to Peacock. I get it for free with my Comcast account and I don’t have to endure Uncle Phil & Bobke.
Win - win!!!
