Race Information

The annual STFU at Sleepy Hollow State Park takes place in the middle of Michigan. Summer Trail Fest Ultra and Half Marathon (STFU) is convenient for those on the east and west sides of the state. With well-groomed trails and extremely generous cutoff times (12:45:00 for the 50 Mile and 11:15:00 for the 50K & Half), this is a spectacular race for your first ultra, seasoned vets looking for a well-executed race, or athletes looking for a personal best. When you cross the finish line, celebrate at the beach with Trivium Racing's post-race STFU barbecue party while cheering for participants on the course!
