Guana 50K and 12K Trail Races

The Guana Research Reserve, nestled in the picturesque South Ponte Vedra region of Florida, hosts an exhilarating trail running experience on Sunday, December 6, 2026. This year’s edition features three distinct race options designed to cater to both endurance runners and those seeking a more manageable challenge.
For serious distance enthusiasts, there are two versions of the 50K event: an individual run that starts at 8 AM sharp, and a team relay format where teams can either tackle the full course together or opt for the 2x25k split. The latter allows participants to share the demanding terrain in smaller segments, making it ideal for those looking to strategize their efforts.
The day also welcomes shorter-distance runners with an invigorating 12K race that begins at 1 PM. This event offers a scenic and manageable route through some of Florida’s most stunning natural landscapes.
Participants can expect a challenging course that winds its way across the diverse terrain within Guana Research Reserve, including sandy trails, marshy areas, and hardwood forests. The reserve is renowned for its rich biodiversity, providing runners with an immersive experience amidst towering trees, vibrant wildlife, and serene waterways.
The event promises to be more than just a race; it’s a celebration of nature and community spirit. Whether you’re chasing personal bests or simply enjoying the beauty around you, this trail run offers something unique for all levels of participants.
Runners will have the opportunity to explore one of Florida's hidden gems while pushing their physical limits in an environment that fosters both competition and camaraderie among athletes from across the region.
