The Innsbrook Half Marathon

The Innsbrook Half Marathon & 10k is a scenic running event held at Innsbrook Resort in Missouri, about an hour from St. Louis. Participants can choose between a 13.1-mile half marathon or a 6.2-mile 10k course, both featuring a mix of pavement and smooth gravel roads through beautiful countryside during peak fall colors.

The certified course offers a challenging yet picturesque experience, capped at 500 runners to ensure small start waves and ideal course density. Runners receive a custom finisher medal, premium long-sleeved shirt, catered to-go lunch, and enjoy live music and cold beer at the finish. The event is hosted by Big River Race Management.
