About the Team

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.

The Geist Half Marathon school program is one aspect of our annual event we are most proud of. Last year, over 1,800 students competed in the actual race. Another 75,000 students were directly impacted thanks to the programs we were able to support through the generosity of our volunteers, competitors, and local sponsors. We are working to build upon this success in an effort to grow our impact on these vital programs, the overall health of our community, and the total number of students we directly and indirectly serve, support, and build into. To date, the Geist Half Marathon, Inc. has donated over $500,000 to Geist area schools.
