The Nationwide Children's Hospital Columbus Marathon, first run in 1978 and held annually since 1980, features a flat, fast course which saw nearly 20 percent of finishers qualify for the Boston Marathon in 2010. The event has sold-out in mid-August the past eight years. There are 7,000 runners in the full marathon and 11,000 in the half marathon, making it one of the largest running events in the United States. For the third straight year, Nationwide Children's Hospital is the beneficiary of the event. More than $2 million has been raised since 2012.
