The Oatlands Invitational features a 5K course run on the grounds of Leesburg's historic Oatlands Plantation. Runners can expect mostly grass, wooded trails, and two creek crossings. It is noted for its fast first mile and large hill which makes or breaks runners at the 2.5 mile mark. The meet is also known for its shotgun blast starts, loud sound system with music/DJ, and outstanding prizes for race winners.|
Every year, over 3,000 runners complete the course within a compact race schedule of 30 minutes per race with some races exceeding 500 runners on the course at once. One junior varsity race in 2012 had 941 finishers.
