The JMF Trails Hillbilly Half returns for its 13th edition on November 21, 2026, inviting runners to explore the rugged and picturesque trails of Jefferson Memorial Forest near Louisville, Kentucky. This race is a tribute to trail running enthusiasts who love challenging terrain and scenic routes. Race Director Todd Shellhammer takes over from his friend Troy Shellhammer, ensuring that this special event continues to honor its roots while delivering an unforgettable experience for participants. The course features steep climbs and descents along the Siltstone Trail, creating a dynamic challenge that tests runners' endurance and resilience. The race kicks off at Horine parking lot with a loop around the lake before descending into Jefferson Memorial Forest's Welcome Center via Yost Ridge Trail. From there, runners tackle the challenging Siltstone Trail, passing Bearcamp Road on their way to an uphill turnaround point. The return journey offers similar terrain but in reverse, pushing runners' limits as they navigate steep ascents and descents. Aid stations are strategically placed at miles 2, 5, 8, and 11, offering a variety of refreshments including sports drinks, water, Coke, cookies, pretzels, chips, peanuts, and peanut butter. Participants should plan to bring their own energy gels as they won't be provided. The JMF Trails Hillbilly Half is known for its challenging course that can significantly extend runners' half marathon times due to the elevation changes and technical trails. It's a race where every step reveals new vistas of natural beauty, making it more than just a test of physical prowess but also an appreciation of Kentucky’s stunning landscapes. Sponsors like Quest Outdoors have been integral in supporting this event since its inception, providing gear for outdoor enthusiasts and fostering a sense of community among runners. Their store at 4500 Shelbyville Road, Suite 133, Louisville, KY is worth visiting if you're looking to upgrade your trail running equipment. Participants should be prepared for an intense yet rewarding experience as they traverse the diverse terrain of Jefferson Memorial Forest. The JMF Trails Hillbilly Half promises a day filled with adventure and camaraderie among fellow runners who share a passion for pushing their limits on challenging trails. Refunds are not available, but Todd is more than happy to defer your registration to next year's event if circumstances prevent you from participating this time around.
