About the race
Half marathon trail race held on November 21, 2026 at Jefferson Memorial Forest in Louisville, KY. This is the 13th running of the JMF Trails Hillbilly Half, organized by Headfirst Performance.
The course begins in the Horine parking area, runs around the Horine lake, then descends Yost Ridge Trail to the Welcome Center where runners pick up the Siltstone Trail. The route continues past Bearcamp Road to a turnaround on the Siltstone ridge, then returns to Horine by the same route. The course includes significant climbs and descents and multiple sections of singletrack.
Aid stations are located at miles 2, 5, 8, and 11 and will be stocked with a sports drink, water, Coca Cola, and a variety of food items including cookies, pretzels, chips, peanuts, and peanut butter. Gels will not be provided, so runners who use them should bring their own. Participants are advised to carry a water bottle and a reusable cup.
Times on this course can be substantially slower than on roads; finishing times may reach about 150% of typical road half marathon times. Refunds are not available, but registrations may be deferred to the following year. Quest Outdoors is listed as a long term sponsor of the event.
