Run on one of the most scenic and beautiful courses in the Midwest, during the peak of fall color in Missouri. Runners and walkers will be treated to 13.1 miles, on a single loop course, with a mix of pavement and smooth gravel roads (think Katy Trail). Cross six dams with scenic views, while running past some of the 100+ lakes found on the Innsbrook Resort. 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 of hills. Consisting of 7.5 miles of gravel and 5.6 miles of paved roads, this course gains almost 1000 vertical feet while rolling over some of the most beautiful countryside in the Midwest.
