Summer Trail Fest Ultra - Laingsburg, Michigan
Summer Trail Fest Ultra (STFU) takes place on June 13, 2026, at Sleepy Hollow State Park in Laingsburg, Michigan. The event is in its fifth year and offers multiple distance choices on natural trail terrain.
The course uses mostly singletrack and is reported to be about 90% well-groomed with minimal technical terrain. The route is described as well marked. Reported cutoff paces include 21:43 per mile for the 50K, 15:18 per mile for the 50 Mile, and 51:31 per mile for the Half Marathon.
Aid stations are described as well stocked with water, electrolytes, gels, and real food options, and drop bag services are available so runners can compete without a crew. There is a post-race cookout and BBQ with burgers, hot dogs, and sides, and spectators may purchase picnic tickets.
Event options include economy packages that omit the finisher medal, custom bib, and race shirt, plus virtual entries that include a medal and shirt. There are ruck categories where participants carry a weighted ruck sack or weight plate carrier and are weighed prior to the event. Race medals are designed to magnetically connect with Winter Trail Fest medals. Visit the organization's website for the most recent information.
