The 21.5K, a Philly Track Jawn

Set to take place on May 31, 2026 at 8am, the inaugural 21.5K is a half marathon(+) (13.3 miles) event that celebrates the culture and history of Philly. Meant to complement the Broad Street Run, held on the first Sunday of May each year, the 21.5K takes place on the final Sunday of May, offering participants a final opportunity to take on a longer distance through the city before the summer heat sets in. The race begins and finishes in North Philly, creating a route that connects neighborhoods, landmarks, and communities across Philly before returning to where it all started.
