About the race
Summer Trail Fest Ultra 50 Mile, 50K, Half Marathon, and 5 Mile – June 12, 2027 Summer Trail Fest Ultra (STFU) is back for its sixth year on Saturday, June 12, 2027, at Sleepy Hollow State Park in Laingsburg, Michigan. This summer trail race is the perfect mix of beginner-friendly and PR-worthy, with smooth, well-marked singletrack and generous cutoffs that make it accessible for both new and experienced trail runners. Whether you’re ready for your first ultra marathon, looking to nail a faster half marathon, or want to test yourself on the 5 mile trail race, STFU delivers a one-of-a-kind Michigan trail running experience. The course features about 90% well-groomed trails with minimal technical terrain, making it an ideal choice for anyone stepping up to longer trail distances. With 21:42/mile cutoffs for the 50K and 15:18/mile cutoffs for the 50 Mile, you’ll have plenty of time to finish strong. Aid stations are well-stocked with water, electrolytes, gels, and real food options, so you can run without a crew and still be fully supported. After the finish line, the fun doesn’t stop. Stick around for a post-race cookout featuring burgers, hot dogs, sides, and plenty of trail camaraderie. Spectators can even purchase picnic tickets, so your family and friends can join the celebration too. Even better? STFU is the summer counterpart to the February Winter Trail Fest (WTF) Half Marathon & 5 Mile in Brighton and Middleville. Each year, the STFU and WTF medals are designed to magnetically connect into one giant finisher medal. You can also register through the WTF + STFU bundle to save 15% off each race while guaranteeing your spot in both events. Why Run STFU?
