 Area Description 

Miami Whitewater Forest offers a visitor center with nature displays and a gift shop. The 4,438 acre park also features multiple trails, including the paved 7.8-mile Shaker Trace trail and 1.4-mile fitness trail, as well as the 1.7-mile Badlands, 0.8-mile Oakleaf, 0.6-mile Tallgrass Prairie and 1.4-mile Timberlakes nature trails, plus two horseback riding trails. Visitors can enjoy a 9-hole disc golf course and play or practice at the Miami Whitewater Forest Soccer Complex in a men's, women's or co-rec league. Shelters, picnic areas and a youth camp area are reservable. The park also includes an 11-acre dog park with play fields, an all-season area and a dog agility course.

​Run for a Cause!

A portion of each registration from each racer and an overall donation from Mountain Trail Series will be given to the CURE JM Foundation. ​Juvenile Myositis (JM), including Juvenile Dermatomyositis (JDM) and Juvenile Polymyositis (JPM), are a group of rare and life-threatening autoimmune diseases, in which the body’s immune system attacks its own cells and tissues. Weak muscles and skin rash are the primary symptoms of JDM, while muscle weakness without a rash is the primary symptom of JPM.

​We feel this foundation is doing critical work to help children who are dealing with this devastating illness. You can help support the cause by donating to the CURE JM Foundation. All donations go directly to the foundation.

​Thank you for your support.​
