Experience the rugged beauty of the Cap Sauers Holding Nature Preserve, the largest tract of undeveloped land in Cook County, Illinois. This challenging trail marathon traverses every inch of the preserve's maintained trail system, including the Yellow, Green, Blue, and Tan trails. While Chicago is known for its flat terrain, this course surprises runners with over 1,000 feet of elevation gain, making it a true test of endurance. The route utilizes wide horse trails throughout, ensuring ample space for two-way traffic and a supportive atmosphere among participants. It is a unique opportunity to explore the wilder side of the region on a demanding, scenic course.
