Fly the course

All 26.2 miles through a model of Sacramento 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. 42.26 km trace whose endpoints match the official Master Map KML 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 0.1% of the certified 26.2 miles; no part of the line passes through a building; 100% of it sits on a mapped road; closest it ever comes to a building wall is 2.4 m.

Note on bridge grades: Where a course crosses a bridge, the elevation now follows the deck rather than the ground underneath it. A terrain model contains no bridges, so it used to sample the riverbed and report a gorge the runner never descends. Decks are held level between their abutments and never allowed to sag below them; a genuine climb across a long span, like the Golden Gate approach, is left exactly as measured. The camber of a long suspension deck is not modelled, so a bridge that really does rise toward mid-span may read slightly flatter here than it feels.
