FLATS Trail Half Marathon

The FLATS Trail Half Marathon is one of the Midwest’s most beautiful and adventurous single-track trail half marathons! The course takes runners from the Thousand Hills State Park Marina through the forests, savannas, and hills along the shores of Forest Lake, with the finish and post-race festivities at beautiful Jackson Stables.

All proceeds from the FLATS Trail Half Marathon are donated to the Forest Lake Area Trail System (FLATS) for the construction and maintenance of trails in Adair County, Missouri.

The race will start at the Marina at Thousand Hills State Park (the flag pole marks the start), and follow the paved road for about 1.5 miles. This is the only paved portion of the event, and is necessary to allow racers to spread out before entering the singletrack. After taking a left onto Thousand Hills Trail, racers will navigate the twists and turns, ups and downs, rocks, roots, and trees for approximately 11 miles. There are a few stream crossings, and inevitably there will be mud in spots. The trail will exit onto Rainbow Basin Trail (County Road 226), where racers will follow a gravel road for the final half-mile into Jackson Stables. There will be mile markers every half mile of the trail.
