Location: Indian Camp Creek Park
2679 Dietrich Road, Foristell, MO 63348
Distances Offered: 40 Mile, 50 Mile
Course Description:
Indian Camp Creek Park, Foristell, MO
The course at Indian Camp Creek Park features a scenic and runnable trail system that winds through rolling wooded terrain, open meadows, and alongside the natural beauty of the creek and surrounding conservation areas. Runners will complete a clearly marked ~3.1-mile (5K) loop, returning each lap to the same central start/finish area and fully stocked aid station.
The trail surface is a mix of dirt singletrack, grass, and packed earth, with gentle to moderate rolling elevation that provides variety without becoming overly technical. The course includes shaded forest sections, occasional open stretches, and smooth flowing trails, offering solid footing and a comfortable rhythm for runners of all levels.
With a peaceful, natural setting just outside the St. Louis metro area, the loop-based format allows runners to settle into their pace, refuel easily, and choose their distance—whether one loop or a full endurance effort. The combination of accessible terrain, scenic surroundings, and centralized support makes Indian Camp Creek Park an ideal venue for both first-time trail runners and experienced endurance athletes.
