Annual STFU at Sleepy Hollow State Park!

Taking place in the middle of Michigan, Summer Trail Fest Ultra and Half Marathon (STFU) is convenient for those on the east and west side of the state. With well-groomed trails and extremely generous cutoff times (20 min/mile for the Ultra and 45 min/mile for the Half), this is a spectacular race for beginners, season veterans, or athletes looking for a personal best. When you cross the finish line, celebrate at the beach with our post-race STFU barbecue party while cheering for participants on the course! Each year, we create a new design where finisher medals from Winter Trail Fest (WTF) Half Marathon and 5 Mile and STFU combine to make one giant medal! Learn more about WTF Westside here and WTF Eastside here.
