Glass City Marathon
Glass City Marathon is a flat marathon in Toledo, USA, held each April. A single loop from the University of Toledo campus past Ottawa Park, west into Ottawa Hills, north to Sylvania, then back via Wildwood Metropark to finish in the Glass Bowl stadium. Late April in Toledo is usually cool, around 4 to 15°C, and the early start can feel colder. Flat courses like Toledo's reward metronomic pacing — the danger is going out faster than goal pace because it feels cheap early.
