50k Challenge:

This course will take trekkers from the starting area,  passing along the Eagleton Road Demonstration Forest trail, and then to the first aid station @ the Eastern Trailhead of the Eagleton Mine Camp Trail.  Following the course, trekkers will make way to the Western Trailhead, and along several other trails, eventually coming back into the Eastern Trailhead before hitting the return trail to the finish.

There are several stretches of the course, including the first & last 5km, which are fairly technical.  Most of the course is very runnable.
