This trail begins at Mountain Rd. and goes up through mature spruce woods to the summit of Blue Hill. The Osgood Trail climbs quite steeply and is technical with all the usual roots and rocks. It is well maintained, but well used, however.
Near the top, as you come to the first bare rock section, you'll see to your left the Becton Trail to Turkey Farm Rd., which is new and not as well traveled. If you do choose to take this trail, it will extend your run by 4 miles. To stay on Osgood Trail, continue heading up until you get to the summit where there is a nice little view to the SW at ~2.3 miles.
