Hattiesburg Half Marathon, 10K & 5K is a signature fundraiser for the Pinebelt Foundation and United Way of Southeast Mississippi, now in its 13th year. More than 1,500 runners from 24 states and two countries take to Downtown Hattiesburg's streets, supported by nonprofit-sponsored miles with interactive cheer stations and storytelling. The field is female-leaning (61/39) and largely local, with 78% of runners based in Mississippi alongside national participation. The race generates an estimated 250,000 social impressions and carries more than 5,400 followers. Sponsors gain exposure through a weekend-long series of activations, including the Finish Fest and Historic Train Depot expo, delivering authentic grassroots brand connection across the Gulf South.
