Pheidippides probably couldn’t have imagined the sporting event he inspired when he ran 26.2 miles to Athens to announce victory in the Battle of Marathon, but the endurance sport will be celebrated in Cincinnati this weekend as the Flying Pig Marathon. Activities begin Friday and run through Sunday. Gear up for the competition with a Health and Fitness Expo at the Convention Center on Friday or by pigging out with a pasta party Saturday. Runners and cheerleaders kick off the race Sunday starting with opening ceremonies at 6:15 a.m. The full marathon starts at 6:30 a.m., with different dashes and distances following. Spectators can watch from the sidelines or during breakfast at the Moerlein Lager House and then head to the finish line for a victory party at Yeatman’s Cove, with food, low-carb beer and more.
