All three race options will take place on single track trails and jeep roads spanning across both the Norris Dam State Park and Norris Municipal Watershed areas. The 25k course and 50k course are identical in that the shorter race goes one loop counterclockwise and the 50k two loops. New this year will be a 5k race that offers challenges of its own and will be worthy of inclusion in this ultra distance festival. The long races will have multiple aid stations easily accessible by road for spectators and people supporting their runners. The 25k option will have a 4 hour time limit and the 50k option will have a 9 hour time limit, with runners required to reach halfway within 4 hours to be allowed to go back out.
