The Riverhead Backyard ReLaps Ultra starting on 28 March 2026 is a "last one standing" multi-lap endurance race.
Participants run one 6.71km lap per hour (starting on the hour). The race is over when only one runner remains to complete a lap. This runner is marked as the winner and only finisher, with all other runners receiving a DNF (Did Not Finish).
The course is through a mix of commercial pine forest in Riverhead Forest with about 90m elevation per lap.
Please refer to the event website for further details about the Backyard Ultra format and rules.
