Last Mamba Standing : October 23, 2027
Last Mamba Standing is an official Bronze Ticket Backyard Ultra held on private property in Eads, Tennessee, just outside Memphis. The event uses a backyard ultra format in which runners must complete a 4.167 miles loop every hour; any runner who fails to finish a loop within the hour or fails to start the next loop is eliminated. The race continues hour after hour until a single runner completes one final loop alone and is declared the winner.
The course lies on roughly 200 acres of wooded trails with rolling terrain and a scenic lake. The loop features approximately 225 to 250 feet of elevation gain per loop. The field is limited to 50 runners. The top 10 finishers from the 2026 edition receive invitations to return, while the remaining spots are intended to be filled by lottery selections aimed at 20 men and 20 women.
For 2027 the event uses a free lottery registration to select entrants; selected runners are charged only if they accept an invitation. The organizers will provide a limited aid station for backup hydration and nutrition, but runners are expected to be largely self supported and may set up personal crew or aid areas. Camping and crew space is available on the property. There are no refunds and no deferrals. Visit the organization's website for the most recent information.
