The annual spring Geist Half Marathon is set for its 16th annual running here in central Indiana this year, and along with the 13.1-mile and 5K distances, the race will continue the 10K distance, first added in 2017. With its tree-lined course around the Geist Reservoir that sits just northeast of the city, it isn’t hard to see what has made this race a popular one — ample views of the 1,800-acre Geist lake throughout most of the course, which takes runners over five bridges and along the winding roads that surround the southern half of the reservoir.
From the starting line on the Olio Road bridge, runners and walkers (the race is open to both) follow the course southward over the bridge and down to the intersection with Springstone Road, where they turn right and head westward through the residential neighborhoods bounded by lakefront homes all around.
