For those of you who have taken on the Challenge in the past.... Welcome Back!!! For those "newbies" out there....get ready for the run of your life. The course is set up to challenge each individual both mentally and physically. There are three major climbs and three major descents covering 4,000 feet of vertical over the 25K course, and it’s filled with vistas, stream crossings, and single track paths. Zach Miller, one of the top runners in the world, declared the Hyner 25k "one of the ‘funnest’ courses in the world" after setting a new course record in 2018.
