Has anyone ridden in Viva Bike Vegas? I'm pretty sure I'm riding it, but I can't decide between the 60 mile ride and the century. I've never ridden a century before, but I do ride quite a bit, and I have time to train. I'm just slightly concerned about the hills and the heat. Even though the ride starts early in the a.m., I'm imagining the heat in Vegas in September will be pretty intense. Does anyone have any input on this ride--or the Interbike industry trade show (that happens the same weekend)?
