This year's Tour of Missouri will include cycling stars Mark Cavendish and Michael Rogers, who will ride for Team Columbia. Team Columbia also said Thursday that 2007 champion George Hincapie will ride with the team if he recovers from a broken collarbone he suffered in the Tour de France. Cavendish was a six-time stage winner in this year's Tour de France. The Briton also won three stages in last year's Tour of Missouri. Rogers is a three-time world champion. The Tour of Missouri starts Sept. 7 in St. Louis and continues across the state before ending Sept. 13 in Kansas City.
