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 distances: a 50K ultra, a half marathon, and a 5-mile race, all featuring well-groomed, scenic trails covering about 90% of the course. The event welcomes both beginners and seasoned trail runners, with generous cutoff times (20 minutes per mile for the 50K and 45 minutes per mile for the half marathon).

Participants enjoy well-stocked aid stations, clear course markings, and a supportive community. Post-race festivities include a beachside barbecue. Unique to this event, finisher medals magnetically connect with those from the Winter Trail Fest, creating a combined keepsake. Visit the organization's website for the most recent information.
