Nature Valley Grand Prix 2013

 Reigning US professional time trial champions Tom Zirbel (Optum-Kelly Benefit Strategies) and Carmen Small (Specialized-lululemon) will compete in their new stars-and-stripes jerseys for the first time this week when the 15th Nature Valley Grand Prix starts Wednesday morning in St. Paul, Minnesota.

Both Zirbel and Small, riding last year for the Minnesota-based Optum Pro Cycling team, won the opening time trial at the 2012 Nature Valley race and eventually took the overall titles four days later. The two new US time trial champions will be joined in Wednesday's opening time trial start house by newly-minted road race champions Jade Wilcoxson (Optum Pro Cycling) and Freddie Rodriguez (Jelly Belly), representing all four new US pro champions.
