The Experience
The Geist Half Marathon series, first run in 2008 and now in its 18th year, offers a scenic tour around Geist Reservoir. Runners can expect stunning water views, tree-covered trails, and waterfront bridges, creating a picturesque backdrop for the half marathon, 10K, and 5K events.
While the course is described as having water views and bridges, one runner noted that by Indiana standards, it's hilly, suggesting it might not be the ideal course for setting personal bests. The field size is moderate, with around 662 finishers recently, drawing participants from about 22 states. Spectator support can be sporadic due to the course weaving through neighborhoods and over bridges.
Participants receive a race shirt and medal, with access to a post-race party. However, runners finishing closer to the 4-hour course limit may find the post-race amenities, including beer, being packed up, even if they finish within the official time limit.
