Rosaryville Half Marathon and 10K Trail Run

Step into the thrill of the season with a running race that promises to invigorate your spirit in the lush expanses of Rosaryville State Park! Perfect for trail veterans or those just starting their running journey, our course through the picturesque Maryland countryside is the ideal place to kick off your racing calendar.

Wind through serene mixed hardwood forests and spree across open fields on trails designed for both speed and enjoyment, while minimally technical terrain means you can push your pace without stumbling over roots or rocks. Choose your challenge: blaze through the half marathon, which strings together the 9-mile perimeter trail, a cozy 2-mile inner loop, and galloping horse trails, or dash through the dynamic 10K course. And as you run, know your strides support City Kids, our charity partner—consider a donation upon registration and race for a cause that uplifts and transforms! Let's lace up our shoes for camaraderie, competition, and charity!
