Riverbend Ultras 12 HR/50K - September 12, 2026
Riverbend Ultras is a trail event at the River Pavilion on Picnic Island in Riverbend Park, Jupiter, FL. The course uses a roughly 3.25 mile loop along the Loxahatchee River on gravel trails, including a section of the Lake to Ocean Trail, passing through oaks and cabbage palms with frequent wildlife sightings such as deer, turkey, turtles, raccoons, and many birds.
Distances and formats:
- 12-Hour: complete as many 3.25 mile Riverbend loops as possible; later in the event runners use the Picnic Island loop.
- 50K: two 0.85 mile Picnic Island loops plus nine 3.25 mile Riverbend loops for a total of 31.2 miles.
- Fun Run: a shorter loop not time tracked.
Awards and items: trophies are awarded for first place male and female in each distance. All 50K and 12-hour participants receive shirts and medals. Fun Run participants pay a nominal fee that covers a donation and a medal and may add a shirt; Fun Run entries are not eligible for awards.
The event is organized as a fat@$$ style outing where runners are largely self-supported; a communal potluck is encouraged. It is operated as a non-profit and proceeds beyond overhead benefit the local Florida Trail Association chapter. No refunds are offered; registrations may be deferred to the following year or forfeited as a donation. Visit the organization's website for the most recent information.
