Located just one hour from St. Louis, runners and walkers will be treated to 13.1 or 6.2 miles on a mix of pavement and smooth gravel roads.

ABOUT THE RACE

Run on one of the most scenic and beautiful courses in the Midwest, during the peak of fall color in Missouri! Hosted by Big River Race Management at the beautiful Innsbrook Resort, just one hour from St. Louis, runners and walkers will be treated to 13.1 OR 6.2 miles on a single loop course with a mix of pavement and smooth gravel roads (think Katy Trail). Cross five dams with scenic views while running past some of the 100+ lakes found on the Innsbrook grounds. But don't let the beauty of this course fool you, it's going to be tough! Innsbrook is hilly, and this course has more than its fair share. A certified course, custom finisher medal with built in bottle opener, long sleeve custom half zip, a catered to-go lunch, post-race entertainment and cold beer at the finish all mean you are not going to want to miss this event. The Innsbrook Half Marathon will be capped at 500 runners, ensuring small start waves and ideal (low) course density. The event will start and finish at the Charrette Creek Commons (pictured below) part of the Innsbrook Resort. Check out the course video!
