Organiser's Description

The Dunes 50k course goes through 13 unique natural communities in 11,000 acres state park. The grueling trails at Jonathan Dickinson State Park will take you on an ultimate adventure as you run in prairie wetlands to the Dunes of Heaven for the 13.1 and the Dunes of Heaven and Hell for the 50K course. Soft rolling sugar sand dunes that will test your willpower and endurance.
Tackle the trails of an imperial Eco-system of natural rolling sand dunes with beautiful views of the scrubs and the Florida intercoastal. Yes, in the brutal “Real Florida” heat.
The Course

The name Dunes is inspired by the beautiful imperial eco-system, “The Scrubs” with its endless rolling white sugar sand. This course will take you on a journey from Pine Flatwoods to the scrubs where you will go face to face with the infamous “Dunes of Heaven” and Dunes of Hell”.
The first 5 miles you will go through pine flat woods with hard-packed dirt some roots and sand. You will cross two wooden bridges – Kitching Creek South and North, followed by two miles through wetland prairie with another bridge crossing and you arrive into the “Scrubs” imperial eco-system.
Here, you will tackle seven miles through white sand dunes that will make you feel like you are going backward while rolling up and down the relentless Dunes of Heaven for the 13.1 & 50k and Dunes of Hell for 50K only.
For as much as the course tortures you, we promise to be nice to you at the finish line. We love to cater our runners with fresh cold organic coconut waiting for you, or if you prefer some stronger hydration we have some craft beer and burgers firing on the grill and other refreshments, for a complete recovery party.

Cut-off for 13.1: 4 hours
