Fly the course

All 26.2 miles through a model of Toledo built from OpenStreetMap: real building footprints, heights and roof shapes, the water, and the course line itself. Scrub it, switch cameras, or let it play.

Route statustraced from the course file the race itself publishes. the MapMyRun route the official course-maps page links

Course line traced from the course file the race itself publishes. the MapMyRun route the official course-maps page links Buildings, roads, parks and shorelines are OpenStreetMap, ODbL, so building coverage varies block to block. Public-domain USGS/USDA aerial imagery and USGS 3DEP terrain are served as static site assets; no paid map API runs in the browser. This is photographic terrain with modeled architecture, not photogrammetry. Bridge approaches, elevations and facade details remain approximate. The organizer's published route is the reference.

Accuracy check: drawn line is within 0.0% of the certified 26.2 miles; 2 samples still cross a mapped building and are unresolved; 73% of it sits on a mapped road; closest it ever comes to a building wall is 0.0 m.

Known issue with this course file: Fixed. The MapMyRun route the official course-maps page links is correct and reports 26.3 miles, but the trace taken from it began 3,810 m early, running a loop of Ottawa Hills residential streets before ever reaching the start line. Trimming exactly that excess leaves 42,191 m against a certified 42,195, starts the course on West Bancroft Street beside the University of Toledo, carries it out through Ottawa Hills and Sylvania Avenue as the race describes, and finishes on Stadium Drive inside the Glass Bowl. USATF certification OH22014DH.
