As we embark on planning our inaugural race series in 2024, here's a preview of some of the races we're looking to bring you.

Jumping Bridge Backyard Ultra
The Jumping Bridge Backyard Ultra is set on Lower Sugarloaf Key, part of the Florida Keys National Marine Sanctuary. This 4mi loop showcases the Sugarloaf Jumping Bridge, views of the Atlantic Ocean, and Keys wildlife. Based on your standard Backyard race, we'll kick off racers on the hour, every hour, until the last person standing finishes their loop!

Not Quite a Hundo (99/100mi)
The Not Quite a Hundo circumnavigates Key West's 11mi outer perimeter. As the name states, this course will loop Key West 9 times, for a total of 99 miles, with the option of adding one more for the 100mi finish. With the race based at Higgs beach, you'll get to experience Key West from morning to night and explore why so many people call this place paradise.
