A friend and me had to go run this trail, we found out about it a couple of days ago and it got quickly placed on the top of the trails to run list so here goes. You will find it when you head North into Sanberdu canyon from Dillon road.
Not all that far after you pass the Sanberdu canyon sign is the only trail you can run on the left hand side
It's about 4-5 miles long, We took our time and were done in about 2 hours tops including getting stuck twice, even broke out the winch the last time is faster than bothering with a strap. Hell of a fun trail but might beat up the Toyota a bit.
