At Oschersleben, Germany, Michael Schumacher's first day of motorcycle racing ended when he skidded onto a gravel pit and failed to finish at the superbike German International Championship on Sunday. The seven-time Formula One champion, who came in 28th in the morning race, was still delighted. "What incredible fun," Schumacher said. "A race like that is lot better than a test, and it was great to prove myself out there." The 39-year-old Schumacher, who retired from Formula One in 2005, started in the last row and was 37th out of 39 riders following electronic problems in Saturday's qualifying. During Sunday's second race, Schumacher had passed enough rivals on his Honda to take 21st place before skidding out.
