Course notes for Grand Teton include a start at the Stilson Lot in Wilson, a route along Highway 22 that joins a paved jogging trail, a pedestrian bridge over the Snake River, and a turn onto Spring Gulch Road before the finish. The Grand Teton 5K is a paved, largely flat loop that starts and finishes at the Stilson Lot.
The Yellowstone half marathon uses town streets, trails and forest service roads. The route features a river bridge, a steep section of about 200 feet through dense woods, technical rocky trails, and mixed downhill and flat terrain; bears are present in parts of the course and participants may carry bear spray. The Yellowstone 5K runs from near Iris Street and Yellowstone Avenue onto forest roads and returns near the expo area.
