Race Information

Join in the fun in historic Belleville, IL (about 20 minutes from downtown St. Louis, MO) for the full and half marathons that are great for both novice and seasoned runners and feature an affordable registration fee, ENTHUSIASTIC volunteers/course support, ample hydration stations, and small town charm with ammenities that match those of a big city race! This annual full marathon is a runner-pleasing, Boston Marathon–qualifying course that includes about 16 miles of city streets and about 10 miles of a portion of a paved biking/walking trail, and both the full and half marathons include America’s longest Main Street and neighborhood roads.
