Whether you walk, run or come just to squeal, the biggest party in town this weekend is at the 12th Annual Cincinnati Flying Pig Marathon. Billed as a marathon for people of all abilities, the Pig attracts about 22,000 racers and 150,000 fans over the weekend. On Sunday, the wheelchair race starts at 6:25 a.m. At 6:30, 13,000 marathon runners and walkers will take to the streets and make their way toward the aptly named Finish Swine.
