Geist Half Marathon

The Geist Half Marathon is one of the most scenic, challenging, and best-supported half marathons in the country. The Geist Half Marathon Inc. is an Indiana non-profit corporation organized to inspire health and wellness in the children in and around the Geist Reservoir community of Indianapolis, Indiana. We believe healthy bodies contribute to healthy minds, and healthy minds result in improved student outcomes and stronger communities. Working closely with runners, walkers, and our sponsors, the Geist Half Marathon raises funds to benefit wellness and fitness programs implemented within our local schools.
