4sta Hike

The 4sta Hike is an annual trail running event held at Loud Thunder Forest Preserve near Andalusia, Illinois, along the Mississippi River. Participants run a challenging 1-mile loop featuring smooth single track, rocks, roots, downed trees, and steep gradients up to 48%. The course offers two options: an easier main trail loop or a preferred harder route with off-trail sections, with elevation gains of 230 to 304 feet per loop. Runners can complete as many loops as they wish within a 4-hour time limit, making it suitable for those seeking a tough, vert-chasing experience rather than a personal record. Aid stations and post-race refreshments are provided, and proceeds support the forest preserve. Visit the organization's website for the most recent information.
