Nestled in Johnston City, Illinois, just 15 minutes north of Marion, Arrowhead Lake Campground sets the stage for an exhilarating endurance challenge. The race unfolds on a meticulously certified 2.07-mile loop around the serene waters of Arrowhead Lake, providing runners with a scenic and largely flat course that features nearly all gravel terrain save for a brief concrete section near the boat ramp. The event offers various distances to cater to different preferences: from an intense 6-hour race starting at 8 AM on October 10th, through a grueling yet rewarding 24-hour marathon kicking off at dawn with a ceremonious start time of 7 AM. The course’s minimal elevation change makes it ideal for those aiming to rack up significant mileage and achieve impressive times. Aid stations are conveniently located near the start/finish line where runners can refuel on a variety of snacks, including chips, candy, fruit, cookies, electrolyte options, hot food items, and water. For participants with specific dietary requirements, it's advisable to bring their own provisions as well. The event offers more than just competition; it also celebrates achievement through custom medals for all finishers who complete at least one official lap before the deadline set on September 27th. Additionally, those who manage an astounding 100 miles in the 24-hour race will receive a distinctive buckle to commemorate their feat. Packing your own gear is encouraged; runners can set up personal aid stations starting from race day morning, complete with camp chairs and small tables to create a comfortable base for long-distance efforts. Alternatively, participants are welcome to visit the main station at regular intervals throughout the event. For those planning accommodations ahead of time, Arrowhead Lake Campground offers camping options or nearby hotels such as Stone Motel in Johnston City, Super 8, Comfort Inn, and Hampton Inn in Marion, all approximately a 15-minute drive from the race venue. As part of the runner experience, chip timing will be provided by SoILL Racing to ensure accurate results. This event is not just about racing; it's an opportunity for community engagement and camaraderie among runners who share a passion for endurance sports.
