2013 and time again to be a part of the Rock 'n' Roll Philadelphia Half Marathon. Come on, who doesn't like flat, fast and fun races. Bands throughout the course keep you going and thousands of spectators make you feel like....well....a rocker! Help us encourage more people to join the National Bone Marrow Registry by enjoying this half marathon. Whether the first time for you, or one of many races, no better way than to add a cause to your efforts!
