Donna Marathon

Registration opens in July on a first-come, first-served basis and stays open until the race reaches capacity. There's no lottery, so you can sign up directly when the window opens.

All proceeds benefit The DONNA Foundation, which funds breast cancer research and provides direct support to breast cancer patients. It's one of the defining features of this race.

Yes, the course is USATF certified and qualifies for Boston. That said, a relatively small share of finishers hit the qualifying standard, so it's a BQ-eligible course rather than a fast-field race.

The time limit is 7 hours, which accommodates a wide range of paces and makes the race accessible to first-timers and charity runners alongside competitive finishers.

The course is essentially flat. It's a loop through the Jacksonville Beach area with a highest point under 30 feet and no meaningful climbs. Wind from the coast is a bigger variable than elevation on this course.

February mornings at Jacksonville Beach are usually in the mid-50s at the start, warming into the upper 60s by midday. It's generally comfortable running weather, though coastal wind can add a factor depending on the day.

The race starts at Seawalk Pavilion in Jacksonville Beach. Jacksonville International Airport (JAX) is the main arrival point, about 18 miles away. Shuttle service runs from the official race hub, and out-of-town runners typically stay in downtown Jacksonville or along the beaches.
