The Stillwater Marathon was a race run in Stillwater, Minnesota, from 2009 to 2011. The race was put on by St. Croix Events. The race featured a scenic, hilly course near the St. Croix River and took place in late May. The race had more than 500 people sign up in 2009, but faced strong competition in the area with other marathons. Although the marathon ceased, several a half-marathons still take place in Stillwater.
