The Frozen Nuts Trail Run takes participants along mostly unpaved paths bordering Lake Cumberland in Pulaski County Park, near Nancy, Kentucky. This mid-winter trail event offers 5K, 10K, and half marathon distances, alongside a 5K run/walk for those preferring a shorter, more relaxed pace. The course is 95% unpaved, emphasizing dirt and hills over road running.
The trails are described as maintained and clearly marked, yet the race incorporates rolling terrain and the demands of cold-weather running. Each participant faces a climb up “finisher hill,” a notable challenge at the end of the race. As a newer event that includes a T-shirt but no prize money, its appeal lies in the trail running challenge itself, not financial reward.
