The Merrimac Miracle Organization is pleased to host the 4th 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. At Darby Creek (for the full marathon), you’ll turn around and head back to London! Did we mention this race is flat? It is crazy flat!

Both the marathon (OH21006DH) and half-marathon (OH21007DH) courses are USATF certified! This course is perfect for that PR or BQ attempt!

Perks: All half marathon runners will receive a high-quality soft vintage style race shirt with the London OH Marathon logo, a finisher medal, and special promotional offers from local businesses. All full marathon runners will receive a full-zip London OH Marathon lightweight hooded sweatshirt, a finisher medal, and swag from local businesses.
