There are four loops, including Torn Shirt and Murray Lake. Murray Lake is the easier of the two and is total of 9.2 miles in length. There are tight singletracks as well as fast sections. I would recommend for the beginner to intermediate riders. You can even cut the loop by 2 miles by forgoing the Lost Loop at the 2.7 mile marker. Torn Shirt is about 6 miles in length and is little bit more technical. Both loops start and return at the same parking area.
