London OH Marathon

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.

At Darby Creek (for the full marathon), you’ll turn around and head back to London! Both the marathon and half-marathon courses are USATF certified!

All full marathon runners will receive a full-zip London OH Marathon lightweight hooded sweatshirt, a finisher medal, and swag from local businesses.
