Yeah, the Vuelta and the US race overlap a bit
The top teams will send a squad to each race
Sky haven't announced there Vuelta team yet but the riders who go to the US race won't be riding the Vuelta
Wiggo is down to ride the Eneco Tour (Belgium) from 12-18 August in the following squad - Bernhard Eisel, Mathew Hayman, David López, Gabriel Rasch, Ian Stannard, Chris Sutton, Ben Swift, Bradley Wiggins. That race is usually live on Eurosport
Froome and Porte in the US - squad - Ian Boswell, Joe Dombrowski, Josh Edmondson, Chris Froome, Peter Kennaugh, Danny Pate, Richie Porte, Kanstantsin Siutsou
I think that race might be on ITV4? or Eurosport
I assume that Uran will be Sky's team leader for the Vuelta as he sat out the Tour de France
