Yes they do. In the lead up to the TOB Raliegh are riding the Tour De Pyrenees, Motorpoint are doing Vuelta a Leon and Mi-Aout Road Race in Brittany. Rapha Condor are also doing the Mi-Aout. Endura are riding Paris–Corrèze.
All have done some continental racing but not enough due to funding (they're mainly aimed at crit racing).
Provisional line ups:
Sky:
Steve Cummings; Russell Downing; Matthew Hayman; Greg Henderson; Geraint Thomas; Bradley Wiggins
Reserves: Chris Froome & Chris Sutton
Motorpoint:
Ian Bibby; Ed Clancy; Jonathan McEvoy; James Sampson; Andy Tennant; Peter Williams
Reserves: Steven Burke; Malcolm Elliott; Andrew Roche
At the end of the day, the way the race is funded means it will always miss out some areas. There's no stages in Yorkshire this as well as no staes in Scotland. If the areas wanted to have the race there then they shoulb bid for it. Unless the organisers change the funding for the race then it's the local councils that need to be encouraged to have the race, not the organisers.
Oh and by the way, a stage through the lake district would be very, very hard. See below....
