Sloth Run PHILADELPHIA 2026

Sloth Run PHILADELPHIA, held in late August, offers several low-pressure distance options in Philadelphia: a 5K, 10K, half marathon, and a Family 1 Mile Fun Run. A virtual option is available for the 5K, 10K, and half marathon. Participants can also select an eco-registration without a shirt for these same distances. The event accommodates a wide range of participants, from short family distances to the 13.1-mile half marathon. Runners must confirm they are fit and trained for their chosen event. The waiver reminds participants to be aware of traffic along the course.
