August 17, 2024: The 19th annual HammerHead Ocean Marathon is one of our two annual events and offers open water swimming for 1k, 2k and 5k distances.

Swimmers will finish just north of the Jax Beach Lifeguard Station. There will be ample water support, hand-crafted awards, post-race food, and helpful volunteers.

Swimmers: Please see the 2024 Letter from Race Director with announcements about this year’s event.
