About the race

Welcome to the 3rd Annual Sombrero Sizzler presented by Sombrero Running Events. Runners and ruckers circle a 1.25 mile loop of 3/4 asphalt road and 1/4 concrete walking path, with a short grassy area at the end, shaded by pine trees for 3, 6, 9 or 12 hours.

The course is pancake flat and fast, on a former active military base (Cecil Field). There will be plenty of fun and heat to go around.

Aid station and food

One main aid station is at the start/finish line in the main pavilion area, with standard Ultra foods and Skratch Electrolyte for hydration.

Food is grilled ALL DAY: breakfast foods, burgers (vegan as well), brats, Italian sausage and BACON. We always try to have vegan options.

Race day schedule and parking
