Cyclo-cross showdown in Portland

Most of the top cyclo-cross racers in North America are heading to Portland, Oregon this weekend for rounds seven and eight of the US Gran Prix of Cyclocross (USGP). Reigning US national 'cross champion Ryan Trebon (Kona-FSA) will go head-to-head with Tim Johnson (Cannondale-Cyclocrossworld.com), the defending USGP series champion, in what should be the most exciting racing of the season. Each currently has two wins in the series thus far.
