I'm not sure what the video options will be, but the action starts today with a massive mountains stage in the Auvergne region of central France. Deets on the flip...
Stage profile thingy:
The Col du Chansert is 13km averaging 5.6%, while the final climb is 13.3km at 6.5% median. More info at the ASO site or at Velo101.com if you read French. Stages 6 and 7 over the weekend will be in the Haute-Alpes with uphill finishes at higher altitudes, so today is perhaps a dress rehearsal. Still, if it's watchable, it'd be great fun.
