Az amerikai WorldTour csapatok Shack, BMC, Garmin - például erősebb sorokat állítottak ki, mint a Giro d’Italiára, de a Leopard a Tour ezüstérmesével, Andy Schleckkel érkezik.
A Rabobank, a Sky, a Saxo, valamint a Liquigas pedig komoly sprinter kontingenssel képviselteti magát, a Team Type 1 színeiben Bodrogi László is indul a versenyen, csapatának kinyilvánítottan a legfontosabb esemény idén a május 15. és 22. között sorra kerülő Kaliforniai Körverseny. A címvédő, ausztrál Michael Rogers ellenben nem indul idén a sprintereknek és a hegyi menőknek is lehetőséget kínáló viadalon.
