Since the second annual USA Pro Cycling Challenge announced the 16 teams set in Colorado's summer cycling spectacular, any cycling enthusiast has been playing the guessing game as to which riders will show up to climb our Rocky Mountains. Would the 2011 champion Levi Leipheimer return to defend his title? Will our Tour de Colorado be the final ride for 15-time Tour de France rider George Hincapie? Might a Schleck brother show up?

The wait is over. Here's who will race August 20 to 26. Bonus: Check back on Thursday, August 17 for 5280's picks for the best spots to watch along the 683-mile race route.
