This year's Lonestar 70.3 is going to be a battle royale. And there's no denying the draw: Lance Armstrong is returning for his second race as a pro triathlete, off the heels of his impressive debut in Panama. The famous Texan will be joined tomorrow by a cadre of top names including Michael Raelert, Marino Vanhoenacker, Tim O'Donnell, and T.J. Tollakson . The women's side is nothing to scoff at either, with the likes of Leanda Cave, Amy Marsh, Caitlin Snow, and Heather Wurtele leading the charge. Here's our pre-race gallery from the expo, which will be followed up with more coverage of the event tomorrow, and some post-race stuff on Monday.
