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.
