The third and least prestigious of the Grand Tours.
Roglic doesn't seem to have many big challengers.
Quest TV showed Polish Border Force instead of the prologue TT (the muppets also showed stage 1 instead of stage 4 of the Giro earlier this year), so I can't comment on that.
Just watching stage 2. Beautiful tarmac, hot, sunny, and barren, like a spaghetti western. Spain is big and empty.
