My effort today on September 28, 2015 was a cumulative time of 3 hours 10 minutes and 56 seconds. My GPS data read 13.02 miles with 5184 feet of ascent and 4921 feet of descent. My route started at the Worcester Mountain Trailhead, ascended Worcester Mountain Trail, and continued south on the Skyline Trail. I then included the out and back to Stowe Pinnacle via Ridge Trail. After returning to Skyline Trail I continued south to Mt. Hunger, White Rock Mountain, finally down Bob Kemp Trail to Middlesex Trailhead. If there is more information on previous traverses, I'd be interested in hearing about them.
