From the organizer
Traverse the 11,000 acres state park. Run through Pine Flatwoods, River swamps, bald cypress, old military base, to the infamous “Dunes of Heaven” and "Dunes of Hell”.
The race name " Dunes" is inspired by the toughest part of the course, an imperial eco-system called "Sand scrub" its endless rolling white sugar sand.
