The inaugural Miami Backyard Ultra brings the backyard ultramarathon format to Miami for the first time on Saturday, December 19, 2026, starting at 8 AM at Miami Marine Stadium & Basin Trail on Virginia Key. Every hour, runners start a 4.167-mile loop, known as a “yard,” and must finish it within the hour before lining up for the next start. There is no set distance or finish time, and the race continues until one runner completes one more yard than everyone else. Runners can enter solo or as part of a duo or team of four, and no previous ultramarathon experience is required. Organized by Frankie Ruiz, co-founder of the Life Time Miami Marathon, together with Carlos Osorio and Breakwater Hospitality Group, the race runs along the waterfront beside the historic Miami Marine Stadium. Registration is open at MiamiBackyardUltra.com.
