About the Geist Half Marathon

Operated by the City of Fishers with Vision Events, the Geist Half has been a fixture on the Indianapolis-area fall calendar for well over a decade. It is the flagship of a race morning that also includes a 10K, 5K, and 1-mile, and it trades downtown Indy for the water views of Geist Reservoir.

Course

The route works the neighborhoods and parkways around Geist Reservoir, crossing waterfront bridges and running long tree-lined stretches with the water in view. The terrain rolls steadily rather than staying flat, so even pacing beats attacking the early miles.

Race-day weather

Mid-September in central Indiana usually brings starts in the upper 50s and finishes near 70, with humidity still possible. The tree cover helps, but the later miles can feel warm on slower days.
