A party on the trails with 50K, 50Mi, 100K, 100Mi, 10 mi and more — the final race of the year just outside Springfield, MO featuring a 2-mile loop on trails, gravel and pavement with base camp at the start/finish.
One aid station at start/finish area. Do not rely on aid station; pack everything needed to finish. On-course "real-ish" food available at main aid station for tired racers.
Pacers may accompany runners starting halfway through their event. Pacers must be over 18, wear a bib, use a headlamp for dark loops, and stay with their runner at all times. No bicycles, motorized vehicles, or unnatural transportation; one pacer per runner at any time. Pacers follow the same checkpoint cutoff rules as runners.
Monthly averages based on historical data (2000–present).
