The Merrimac Miracle Organization is pleased to host the 6th Annual London OH Marathon as a fundraiser for Merri-Mac Park. We are raising funds to further improve the park by adding play equipment, recreational paths, sports fields, etc.
Format: The full and half marathon race events will start promptly at 7 am and the 5K at 7:15 am. The course will remain open for 5 hours after the last competitor starts.
Course: The start and finish will be located at Merri-Mac Park. All course maps can be viewed here. The flat, tree-lined scenic rails will take you toward Darby Creek Metro Park. The full marathon repeats the course twice. Did we mention this race is flat? It is crazy flat!
Aid stations and port-o-johns are spaced at every 2-2.5 miles along the course. Aid stations are stocked with water, Gatorade, and GU gels.
Both the marathon and half-marathon courses are USATF certified! This course is perfect for that PR or BQ attempt! YES!
