The Innsbrook Half Marathon

The Innsbrook Half returns for 2023 AND we've added a 10k option for those looking a shorter distance. Run on one of the most scenic, beautiful and challenging courses in the Midwest during the peak of fall color in Missouri! Hosted by Big River Race Management at the beautiful Innsbrook Resort. 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. A certified course, custom finisher medal, premium long-sleeved giveaway, a catered to-go lunch, live music and cold beer wait at the finish - you are not going to want to miss this event! The Innsbrook Half Marathon & 10k will be capped at 1000 runners ensuring small start waves and ideal course density. The event will sell out in 2023, so don't wait, sign up today!
