Back Cove Backyard Ultra

The Back Cove Backyard Ultra is a unique endurance running event held in Portland, Maine, on the scenic Back Cove Trail. Participants run a 4.167-mile loop every hour on the hour, continuing until only one runner remains. The course features a mostly flat, non-technical 3.5-mile gravel loop along a tidal estuary, with an additional 0.6-mile stretch on the Bayside Trail to meet the standard backyard ultra distance.

The event offers two aid stations—one staffed at the start/finish and one unstaffed in Payson Park—with water, snacks, and basic first aid. Free parking and volunteer support contribute to a welcoming, community-focused atmosphere. Visit the organization's website for the most recent information.
