We were told that our 50k was the hardest trail race out there. We took this info to heart....and decided it needed to be harder. So we added another 1.926 miles. (you are welcome to go the extra few steps to make it an even 2 miles) 

After completing three 11 mile loops, you will be given your medal, finishers' long sleeve shirt &, if you are over 21) a cold beer.
