Glass City Marathon
Toledo, OH · Sunday, April 25, 2027
Named for Toledo's identity as "the Glass City," a nickname the city earned after Edward Libbey moved his glass company there in 1888 and companies like Libbey and Owens-Illinois built a global glassmaking industry on the Great Lakes' natural gas and silica-rich sand. The course itself is flat, point-to-point, and built for speed.

Why runners choose this race
A point-to-point course around Toledo, OH, with very little meaningful elevation change.
