The 15 and 22 mile rides have been redesigned to be more family friendly. The new courses are nearly flat and the 15 mile course avoids road traffic altogether! Both routes follow the newly paved "Fish Lake Trail" from the trailhead at the foot of Sunset Hill out to Scribner Rd and back. The 22 mile route is the same as the 15 mile route with the addition of a 3.2 mile section from SFCC along Government Way past the cemeteries and returning the same way.
For more information about the trail, here is the 15-mile Fish Lake Trail Map.
