The City of Fishers has announced the return of the Geist Half Race Series, Indiana’s premier waterfront running event, for its 18th year. The races are scheduled for Saturday, September 12, 2026, along Geist Reservoir.
Registration opened today (Tuesday) with special New Year’s pricing available through 11:59 p.m. on January 1. City officials said early registration allows participants to secure the lowest price offered for the 2026 event and begin planning for their fitness goals for the coming year. Registration prices increase January 2.
The Geist Half Race Series offers multiple distances designed for runners and walkers of all experience levels, including a family-friendly 5K, a 10K, and a 13.1-mile half marathon featuring approximately 800 feet of elevation. All courses run along the Geist Reservoir waterfront. Participants receive a race medal, race shirt, and a drink ticket for the post-race celebration.
The 2025 event drew approximately 2,500 participants from 26 states. The race also gained national attention when four former Anderson University cross country and track athletes set a Guinness World Record for the fastest half marathon run in a four-person costume, completing the course dressed as a caterpillar.
Several new and returning features are planned for 2026. Youth participants will be able to run or walk in the 5K for a flat $20 registration fee, with that price remaining unchanged throughout the registration period.
The race will again partner with the Fishers Arts Council on a community art contest to design the official race shirt. The contest is open to current high school juniors and seniors, with submissions accepted from January 5 through February 5, 2026. Finalists will be selected through community voting both online and in person at Fishers City Hall and the Fishers Community Center in late February.
The VIP Perks package, which sold out in 2025, will return next year. For an additional $58.99, runners can purchase reserved race-day parking, VIP race gear, access to a post-race recovery zone, VIP gear check, and an extra drink ticket for the post-race party.
Applications are also open for the Geist Half Marathon Ambassador Program. Ambassadors assist with race promotion through social media and at community events in exchange for free race registration and race-related merchandise. Applications are due by January 30.
