On 6 December 2025, Jackson County Ultras returns with multiple distance options: 100K (solo or 2-6 person relay), 50K, and 10 miles. The race is held at Pyoca Camp in Brownstown, with the course running through rugged forest terrain, ridgelines, lakes, and varying trail surfaces. In 2025, the course direction is set to run counterclockwise (alternates each year). Ultra runners must carry a live tracker, and the 100K distance has a 24-hour cutoff. The event provides well-stocked aid stations, indoor heated facilities, camping and cabin packages, post-race meals, and strong community support. With ambitions to become the Midwest Western States 100K qualifier, Jackson County Ultras challenges endurance runners while creating a memorable wilderness race experience.
