Geist Half Marathon The Geist Half Race Series is held annually each September in Fishers, Indiana. Learn more at GeistHalf.com

Indiana's premier waterfront race features 4 race distances: the iconic half marathon, 10K, and family-friendly 5K and 1 Mile Race! St.Vincent Geist Half Marathon is excited to have the opportunity to work with area schools again this year to promote this fun and healthy event to children. The St.Vincent Geist Half Marathon school program, and the far reaching benefits it brought to the over 1,500 youth who participated, is an aspect of last year’s event that we are most proud of. We are working to expand upon this success so as to continue to support the Foundations efforts to combat the growing problem of childhood obesity.

Three weeks later, and we’re still smiling about race day. 🏃‍♀️🏅

This year’s Geist Race Series brought runners of all ages to the course — including plenty of big finishes in the 1-Mile. Whether it was a first race, a family run or another finish line crossed, the 1-Mile proved you don’t need 13.1 miles to make a race-day memory.

A special thank you to our HSE student extern, Drew Kaplan, for helping capture the people and moments that made the day so memorable. 🏁

Congratulations to the Indiana Army National Guard for winning this year’s Water Stop Showdown at the Geist Race Series!...
