The name Dunes 100 is inspired by the last 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 flatwoods 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 and Dunes of Hell.

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.
