Native San Franciscan Kelcey Harrison is a major marathoner and lung cancer advocate. On July 30th 2012, after leaving her job at New York County’s District Attorney’s office, the 24 year old Harvard grad set out on her Great Lung Run – a 3,500-mile run from New York’s Times Square to downtown San Francisco. Harrison expects to arrive in November 2012 and will be blogging and tweeting her adventures until then. Harrison also loves Charades.
