Yankee Springs Fall Festival is a trail running event held at Deep Lake Campground near Middleville, Michigan, starting and finishing within the campground. Participants can select a 10k-ish loop, a 25k loop, or a 50k composed of two 25k laps. The shortest race measures closer to seven miles than a standard 10k, indicating a preference for trail-running flexibility over road-running exactness. The courses feature rolling single track in the Yankee Springs area. The 10k-ish loop has one aid station, while the 25k route includes four. Aid stations provide water, Gatorade, and a selection of sweet and salty snacks. Runners in the 50k may have pacers during their second lap. Camping is integrated into the event; Deep Lake provides primitive sites adjacent to the start and finish, and the nearby Gun Lake Campground offers sites with running water and electrical hookups. Race entry includes a long-sleeve tech shirt or buff. The event utilizes trails also used for the organizers' spring and winter races.

The Sandhill Crane All Trail Half Marathon/10K/5K takes place at Dr. T. K. Lawless County Park, an 820-acre park in Vandalia, Michigan. The event features a half marathon, 10K run/walk, 5K run/walk, and a 1K kids fun run, all utilizing unpaved park trails. The half marathon is a 13.1-mile non-repeat route, ensuring runners experience new terrain throughout. The course winds through forest and field, alongside streams and small lakes, with six bridge crossings. It is not flat, starting around 900 feet and climbing to a high point near 1,000 feet, incorporating hills into the trail running. Sandhill cranes are common in the area, inspiring the race's name and offering participants a chance to spot one. The event is limited to 500 participants, uses chip timing, and provides fruit at the finish. Finishers get custom long-sleeve performance shirts, top finishers receive laser-cut wood awards, and second and third place finishers in each age group receive medals. Proceeds benefit Dowagiac Rotary charities and Cass County Parks.

The Dowagiac All Trail Turkey Trot takes place entirely on unpaved trails at Southwestern Michigan College in Dowagiac, Michigan. This November trail race offers 10K and 5K distances that begin simultaneously, along with a 1K children's run scheduled afterward. The event limits registration to 500 participants, employs chip timing with live results, and maintains a practical local-race format: tiered entry fees, finisher shirts for pre-registered runners, and timing services provided by Mac's Sports Timing. The course follows the college's trail system at 58900 Cherry Grove Road, noting an elevation of 761 feet at its highest point. This distinguishes it as a campus-trail run rather than a road race with a minor unpaved section. Southwestern Michigan College supports the event, Ron Gunn of Cairn Stone Adventure Tours oversees its direction, and the race originated in 1967, establishing it as a long-standing Dowagiac tradition. Adults may run or walk the 5K and 10K, and the children's run provides a shorter option for younger participants, awarding ribbons.
