Covid Update

We are suspending registration payments as Trailhead Ultras is going Virtual the rest of 2020. Caloosahatchee Ultra cannot be run as a virtual race. It just wouldn't be the same running anywhere else. While we maintain a glimmer of hope we will make a final decision on October 1st. Thank you for understanding.


The 8th Annual Caloosahatchee Ultra 50k and Keith Carlton Memorial 25k is run on an exciting 10.5 mile loop counterclockwise on varying terrain with beautiful views, rolling hills and some tough technical stretches in Caloosahatchee Regional Park. The course will run the perimeter of the North side along Green, Black and Blue trails.Tailwind Nutrition will be providing the electrolyte drink for all runners. There will be two fully stocked aid stations with all the regular goodies ranging from chips and pretzels to M&M's and Gummy Bears, PB&J, potatoes, and even bacon!! There will be a mini Aid Station out at the entrance to the Far East with at least water to help get you back to the Tree of Life A/S. Park has a no alcohol/no dogs policy so discretion is necessary.
Back again for 2019....pick your shirt style!!! Register before 11/20 and you can select what type of shirt you want. Pick from Men's or Women's style tech shirt or singlet.
