The London OH Marathon is a small road marathon in London, Ohio. The 2027 edition is Saturday, April 17, with the marathon and half marathon starting together at 7:00 AM at Merri-Mac Park. The course is flat and tree-lined, runs along the rails toward Darby Creek Metro Park, and marathoners cover it twice. The marathon and half marathon courses are USATF certified, so the marathon counts as a Boston qualifier. Marathon finishers receive a finisher medal and a full-zip lightweight hooded sweatshirt. Entry is through RunSignup, and everything the race raises goes to improving Merri-Mac Park, including play equipment for kids on London's south side.
