Garmin Toledo Marathon
Race Day Weather
Warm start, moderate wind, chance of rain, high humidity
Starting at 67°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Moderate winds around 12mph may affect pacing on open sections of the course. There's a chance of rain, so have a backup gear plan ready. High humidity (91%) will make it harder to cool down through sweat — increase fluid intake accordingly.

Race Info
The Garmin Toledo Marathon is an annual marathon, half marathon, 10K and 5K that starts and finishes in downtown Toledo, Ohio, at the intersection of Summit Street and Jefferson Avenue. The marathon course crosses the Maumee River twice and passes through Glass City Metropark, Rossford and Perrysburg before returning downtown. It is a USATF-certified, Boston Marathon-qualifying course with 590 feet of total elevation gain and a 6.5-hour cutoff. Garmin launched the race in September 2025 as one of two inaugural stops in its wholly owned Garmin Marathon Series, produced locally by Run Toledo.
