Lovely forest runs up a somewhat lesser-used trail on the west side of the Bridger Range.  Courses will be approximately 1, 3, and 5 miles, and will be basically out-and-back (or, perhaps, up-and-down?) on the main Truman Gulch trail.

To reach the start at Truman Gulch trailhead, take Springhill Road north from near where  I-90 and North 19th Avenue intersect.  Just past mile marker “6”, turn right onto Penwell Bridge Road East.  About halfway along, the road turns to gravel.  At the end of Penwell Bridge Road, turn left onto Walker Road, and drive about 1.4 miles north, then turn right onto Forswall Road and drive to the trailhead parking at the very end.  Should take 20-30 minutes from I-90 at 19th Ave.
