Jupiter, FL
This trail ultra marathon promises to be one of Florida's most unique, and challenging, trail runs. The race will be held entirely within the Jupiter Ridge Natural Area in Jupiter, Florida. We have designed a 3.45 mile loop which you'll run 9 times for 31.05 miles!
There is a 9 hour cutoff for this event due to the restrictions of hours of operations imposed by the Palm Beach County Environmental Resources Management team. Jupiter Ridge Natural Area is an environmentally sensitive site and we must abide by the restrictions inherent to their protection of the area, and the species of wildlife and plants occurring within the site.
