Run on one of the most scenic and beautiful courses in the Midwest during the peak of fall color in Missouri! The Innsbrook Half Marathon will be your chance to run a real half marathon on a real course while keeping safety a priority. Hosted by Big River Race Management at the Innsbrook Resort, just an hour from St. Louis, runners and walkers will be treated to 13.1 miles on a mix of pavement and smooth gravel roads. A certified course, custom finisher medal, long sleeve custom half zip, a catered to-go lunch, and cold beer wait at the finish - you are not going to want to miss this event! The Innsbrook Half Marathon will be capped at 1000 runners ensuring small start waves and ideal (low) course density.
