Embark on an exhilarating trail adventure at the Rosaryville Ramble 5K/10K/Half, set for Sunday, February 22, 2026, in the picturesque Rosaryville State Park in Upper Marlboro, MD. This event offers a unique opportunity for runners of all levels to tackle 5K, 10K, or the newly added 13.1-mile half marathon distances, marking a fresh addition to the park's racing calendar for 2026. The course, known for its fun yet challenging nature, is not overly technical, making it an ideal early-season trail run. Runners will traverse a scenic mix of single-track trails and paved/gravel roads, winding through beautiful mixed hardwood forests and open fields. Expect twisty, relatively smooth, fast trails complemented by rolling hills that add a dynamic element to the run, with the half marathon featuring approximately 1,000 feet of elevation gain, the 10K around 500 feet, and the 5K with about 250 feet.

Runners will find ample support along the way, with the half marathon boasting nine aid stations, the 10K offering four, and the 5K providing two. All aid stations are stocked with water and Gatorade, with one half marathon aid station also offering snacks. The race is staged from Pavilions 1 and 2, with convenient parking in adjacent grass fields, and the park entry fee is covered for participants. Typical race day conditions in late February see highs around 49F and lows near 30F, with a low chance of precipitation, creating crisp, invigorating running weather. Finishers will be celebrated with a medal and a technical event shirt, making the Rosaryville Ramble a rewarding experience for every participant.
