This is a loop that has 70 meters of elevation, mixed 30% trail, 30% asphalt and 40% gravel. As the start is at 18.00 you will just after 2 hours be running in the dark and the night with low temperature below +10 is common. But just go one more loop and you will soon hear the birds singing and see the sun rise.
Last man or woman will be the winner of TEC Backyard Ultra, there can be only one. How far are you willing to run?
