The Willis River 50k or less Fat Ass returns again this year. The race features two options: a 50k and a 35k. The 35k runs much of the Willis River Trail. The course features stream crossings, rolling hills, and a guarantee of wet feet! Those running the 50k will run the 35k, return to the start and then run the Bear Creek 10 miler portion.  

The cost of the race is free. However runners are asked to bring a food donation to share with other runners. The Race Director will provide water, portajohn, and mark the course. Donations are appreciated to cover the cost of the permit, insurance and portajohn.
