Backyard Ultra in Rolla Mo to raise money for the 988 Suicide Prevention Hotline. This is a traditional backyard ultra race with a day loop on the dirt trail and a night loop on the paved trail. Each loop is 4.167 miles. Runners must finish each lap in under an hour. Laps will start every hour on the hour. The trail is beautiful! We have pavilions at the start line. Feel free you make yours right at home. Last year someone brought a carpet, couch and Christmas lights! We have bathrooms and water stations at the start point and 1/2 point on both day/night trails. We want to see you run farther than you ever have before!!
