2026 Rosaryville Ramble 5k/10k/Half

Lace up your trail shoes for the 2026 Rosaryville Ramble 5k/10k/Half, an exhilarating early-season trail race set for February 22, 2026, in the beautiful Rosaryville State Park, Upper Marlboro, MD. This event, organized by Bishop's Events, is renowned for its welcoming atmosphere and courses that are fun and challenging, yet beginner-friendly. Runners can choose from three distances: a Half Marathon (approx. 13.5 miles), a 10K (approx. 6.7 miles), or a 5K (approx. 3.6 miles), each winding through scenic mixed hardwood forests and open fields. You'll experience twisty, relatively smooth, and fast single-track trails with rolling hills, offering stunning views of Maryland's natural beauty without being overly technical. Typical race day conditions in late February present cool temperatures, with highs around 49F and lows near 30F, and only an 11% chance of precipitation.

The Half Marathon course takes you on an adventure incorporating the 9-mile perimeter trail, a 2-mile interior loop, and wide-open horse trails, accumulating approximately 1,000 feet of elevation gain. The 10K+ runners will enjoy about 5 miles of the perimeter trail and over a mile of horse trails, with roughly 500 feet of elevation gain, while the 5K explores parts of the perimeter and equestrian paths, gaining around 250 feet. Aid stations are strategically placed throughout the courses, with nine on the Half Marathon+, four on the 10K+, and two on the 5K+, all providing water and Gatorade; one half marathon aid station also offers snacks.

The race starts and finishes at the convenient Pavilion picnic area within Rosaryville State Park, with parking readily available in adjacent grass fields. Bishop's Events is celebrated for its well-organized, albeit smaller, races with a friendly vibe, making this an ideal choice for runners seeking a supportive environment and a picturesque trail experience. Beyond the run, the event proudly supports City Kids, a dedicated charity partner.
