Fly the course

All 26.2 miles through a model of Louisville 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.

Course line a community trace of the current course; the official certified course is on the race's site. best-fidelity trace of the current course; endpoints match the official 2027 map 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 0.2% of the certified 26.2 miles; no part of the line passes through a building; 99% of it sits on a mapped road; closest it ever comes to a building wall is 0.5 m.
