Summer Trail Fest Ultra

The Summer Trail Fest Ultra (STFU) is a trail running event held at Sleepy Hollow State Park in Laingsburg, Michigan. Scheduled for June 13, 2026, it offers three race distances: a 50K ultra, a half marathon, and a 5-mile run. The course features 90% scenic, well-groomed trails with generous cutoff times, making it suitable for both first-time ultra runners and seasoned athletes aiming for personal records.

Participants enjoy well-stocked aid stations, clear course markings, and a supportive trail community. After the race, a beachside barbecue celebration with food and drinks is held. The event also includes ruck divisions and virtual race options, and finisher medals magnetically connect with those from the Winter Trail Fest.
