Heritage Harbor parkrun is more than just a race; it's a community gathering dedicated to promoting fitness and well-being. Organized entirely by dedicated volunteers, this family and dog-friendly event (leashed furry friends are welcome!) emphasizes fun, community spirit, and an active lifestyle. After crossing the finish line, participants are often encouraged to join a post-parkrun coffee or breakfast, sometimes held at the local Red Dog Grill, further enhancing the welcoming camaraderie that defines this unique Ottawa tradition.
