2026 TIAA Philadelphia Marathon

The Philadelphia Half Marathon, now the TIAA Philadelphia Marathon Weekend, drew nearly 12,000 half-marathon finishers in its most recent edition, with runners coming from approximately 53 states. The event, now in its 19th year, has earned a reputation as a fast, Boston-qualifying course (for the marathon) that also serves as a PR haven for the half. About 19% of runners return year after year.

The course winds through Philadelphia's historic streets, passing iconic landmarks like the Liberty Bell and Independence Hall, then hugs the Delaware River waterfront. The flat, paved route is USATF certified and designed for speed, making it a favorite among runners chasing personal bests. Closed roads and enthusiastic city crowds provide constant energy.

The race finishes near the Philadelphia Museum of Art, the same spot as the marathon, with a festive post-race party. The sizable field of over 10,000 half marathoners creates a big-race atmosphere while still offering personal space on the wide boulevards. For a destination race that combines history, city vibe, and a chance at a fast time, this is a top pick.
