Race Info

The Half Marathon is a point-to-point race from Jones Park in Gulfport to downtown Biloxi on the Sunday of race weekend. It follows Highway 90 east along the Gulf of Mexico, the same road the full marathon uses for its second half, with unobstructed views of the beach. The USATF-certified course is flat, passes the Biloxi Lighthouse and the Beau Rivage near the end, and finishes inside the ballpark in downtown Biloxi.
