DES MOINES, Iowa (AP) – The 103rd Drake Relays begin with a full schedule today (Thursday), though concerns about cool temperatures and rain might prompt some of the Olympic hopefuls to sit out.  Meet director Brian Brown says he’s hopeful that a packed Drake Stadium and the aura associated with one of the nation’s top meets will push those athletes to compete no matter how bad the conditions are.  Des Moines native Lolo Jones, decathlete and Olympic gold medalist Bryan Clay and Iowan Jenny Simpson, the world champion the 1,500 meters, will headline the meet.
