There will be two half marathon start times since the National Park Service limits the number of starters at one time to 100. Half Marathon Wave 1 will start at 8:00AM, and Half Marathon Wave 2 will start at 8:30AM. The marathon starts at 7:30AM.
This race takes place in its entirety in Washington DC on the flat dirt and crushed stone surfaced C&O Canal Towpath. 3.28 miles of the towpath will be used for this event. Runners will head southeast from the start to the Francis Scott Key Bridge at which point runners will turn around and head northwest on the towpath. After running 3.28 miles northwest, runners will again turn around and head back southeast towards the start/finish line. Upon reaching the start/finish line runners will have completed a quarter marathon – or one course loop. Half marathon runners will run this course loop twice and marathon runners will run this loop four times in order to record finishes in their respective races.
