PARIS, France -- A French pole vaulting champion ran naked with his pole through the streets of Paris and posted the video on the Internet, hoping to draw attention to his quest for a new sponsorship deal. Romain Mesnil, who won a silver medal at the Athletics World Championships in Osaka, was sponsored by Nike but says his contract expired last year and was not renewed. It's the crisis," he wrote on his Web site. Many athletes have reported difficulties obtaining corporate sponsorship as companies cut costs because of the global economic downturn. In his video, Mesnil runs with his pole as if preparing for a vault at tourist spots like Montmartre and the Pont des Arts across the River Seine. A black square has been added to the footage to cover his groin area.
