The Mercy Health Glass City Marathon is a spring road marathon in Toledo, Ohio, run on a Sunday in late April and organised by the Toledo Road Runners Club. It starts at 6:30 am on Bancroft Street near the University of Toledo's North Tower, circles the campus past Ottawa Park, continues west into Ottawa Hills and finishes on the field inside the university's Glass Bowl stadium. The organisers describe the course as having little elevation change on smooth paved roads, and it is USATF certified. The course stays open for 6.5 hours, which means holding roughly a 15-minute-per-mile pace. A half marathon, a five-person relay, a 5K and a kids' run share the weekend, which drew 6,642 participants in 2026, including 1,474 in the marathon. The first Glass City marathon was run in 1971, and the race celebrates its 50th running in April 2027. In 2026 Vincent Mauri won on his marathon debut in 2:05:54, which the organisers call the fastest debut marathon by an American and the fastest marathon on Ohio soil. It is the course record. The women's record is 2:35:37, set by Alyssa McElheny in 2025.

The Race
Toledo
Runners first gathered in Toledo for this marathon in 1971, and the race became one of America's best-known spring marathons. In 1983 it was titled the Pepsi Challenge Glass City Classic Marathon, and afterwards it fell dormant for six years. The organisers count April 2027 as its 50th running.
In April 2026 Vincent Mauri of Warren, Ohio ran his first marathon at Glass City and won in 2:05:54. He broke the previous course record of 2:19:31, set in 2025; the organisers call it the fastest debut marathon by an American.
