Event Details

Have the time of your life completing 13.1 miles! Athletes will start along the Benjamin Franklin Parkway in the cultural Museum District and wind through Philadelphia’s most scenic and historic neighborhoods.

From the history-steeped streets of Old City, through one of the liveliest stretches of Center City, across the Schuylkill River into University City, up through the bucolic trails of Fairmount Park, and back down to canvas the banks of the river before finishing in front of the renown Philadelphia Museum of Art.

The half marathon was added to Philadelphia Marathon Weekend in 2006 and has seen an increase in athletes every year since. Whether as a test-run for first-time marathoners or as a challenging race along a scenic course, the Dietz & Watson Philadelphia Half Marathon has given thousands of athletes the opportunity to take on the Philadelphia Marathon Weekend on their own terms.

There are course check points at the 4.3K, 10K, 15K and 20K marks, and fluid stations and spectator overlooks are set up throughout the course.
