Columbia, Illinois (United States of America) - "American Bottoms 100". This is a unique road ultra on a beautiful course, following the Mississippi River as you run through the historic American Bottom. Race headquarters is in Columbia, Illinois, just outside of St. Louis, Missouri. The race offers a 110-mile and a 55-mile option. The course will loosely follow the American Discovery Trail and the Kaskaskia-Cahokia Trail, Illinois' first road. You’ll watch the sun rise over the Illinois bluffs while running on levees and deserted backroads, from Columbia to the confluence of the Kaskaskia and Mississippi Rivers. You’ll make your way through many historic sites, including Piggott's Fort, Fort de Chartres, and the town of Prairie du Rocher. This is a flat and fast course with generous cut-off times, plenty of aid stations, and a friendly atmosphere. It will make a great first hundred miler or a chance for you to set a new personal record at this distance. So, if you're interested in a no-frills ultra with a low entry fee, then come test yourself this spring on the American Bottom.
