Riverbend Ultras 12 HR/50K

Riverbend Ultras is a community trail event in Riverbend Park at the River Pavilion on Picnic Island in Jupiter, FL, organized by Mule Racing and scheduled for September 11, 2027. The course follows gravel trails along the Loxahatchee River and includes a section of the Lake to Ocean Trail through oaks and cabbage palms. Participants may see deer, turkey, turtles, raccoons, and various birds along the route.

Distances and formats include:

  • 12 hour: as many 3.25 mile Riverbend loops as completed in the twelve-hour window.
  • 50K: two 0.85 mile Picnic Island loops plus nine 3.25 mile Riverbend loops (31.2 miles).
  • Fun Run: roughly a 3.2 mile loop along the Loxahatchee River on gravel trails.

All 50K and 12 hour participants receive shirts and medals. Trophies are awarded for first, second, and third place male and female in each distance. Fun Run entries pay a nominal fee, are not timed, and do not qualify for awards; a shirt option is available.

There are no aid stations; runners must carry food, water, and fuel. Participants have access to a large tiki hut with tables or may bring 10' x 10' pop up tents. This is a nonprofit event; proceeds beyond overhead benefit the Wounded veterans relief fund. No refunds are offered; registrations may be deferred to the following year or forfeited fees will be donated. The event will honor those lost on September 11, 2011.
