Race planning
Plan Miami Backyard Ultra
Use the listed edition as your starting point. Each tool keeps imported race facts separate from the targets and assumptions you choose.
Edition notes: Registration is open on RunSignup at $249 until December 14, 2026, or until the 500-runner limit fills; refunds are not allowed. Parking, packet pickup, basecamp footprints, crew access, aid and the final measured course map are still being finalized and will be published in the Athlete Guide before race weekend. Big's race page lists the race without a ticket category, and the organizer's FAQ says: "A calendar listing does not by itself establish a championship qualification or ticket status." Yardlore lists no earlier edition.
