Course Limits

We require that runners and walkers be properly prepared and trained to finish the Halfathon within 4 hours (18 minute/mile pace). Please note that 4 hours after the start, course support ((i.e. aid/water stations, volunteers, course marshals, clocks, etc.) is not guaranteed. The 5k runners and walkers should be finished within the 4 hour time limit for the halfathon.

Course Highlights

  • Both races are staged entirely in Fort De Soto Park, recognized as one of the best beaches in the nation.
  • The course features a loop for the first 3.1 miles of the race, bringing athletes back through the start line.
  • The rest of the course is an extremely flat, out-and-back tour of Fort De Soto Park, mostly on paved recreational trails.
  • With a start time about 30 minutes before sunrise to avoid warm weather, the first portion of the race will take place in the dawn.
  • Sunrise should be directly ahead of our athletes before the turn-around at East Beach.
  • Check out the course map for the precise route.

No Strollers, Bicycles, or Dogs

All our races are sanctioned and insured through USATF for runners, joggers, and walkers ONLY. Strollers, skaters, skateboards and bicycles are NOT allowed on the course during our races.

USATF Certification

Both courses have been precisely measured and documentation provided according to USATF requirements, certifying our courses as accurately measured.


Official results will be sorted by Net Time. Both Net and Gun Times will be provided for all athletes.


  • We offer Gatorade and water at 7 aid stations along the halfathon course, with the first located near mile 2, which will serve as the only aid station for the 5K. Athletes who feel they will need additional hydration than what we provide are welcome to make their own arrangements, such as carrying additional fluids or having friends meet them along the course.
  • Fresh Florida oranges will be available at six aid stations, starting near mile 4.
  • Medical support is available from ambulances stationed along the course, and at the finish line. If you need medical assistance, the ambulances will be mobile and ready to respond.
