Industrial Disease is a steep, technical singletrack that starts off of the Rainbow-Sproat Flank
. The trail is steep and flowy, with rock rolls and drops through tight trees, often on very loose dirt and rocks. There are some long steep rock faces to negotiate on this trail that would hurt if you fell. Some tiny sections of pedaling break up the downhill, but generally it's just a steep downhill.
At the end of the trail connect onto Danimal or one of the many other trails to create a great loop.
