As the first marathon held entirely within city limits, it emphasizes community support and inclusivity for runners of all paces. Participants can choose to tackle the full 26.2 miles solo or organize a relay team with flexible leg distances. With a no-frills, welcoming atmosphere, the event encourages everyone to join in, whether by running, volunteering, or cheering from the sidelines.
