"The Adena Trace is 25 miles total in length and forms a complete circle around the southern half of Brookville Lake. In 2002 volunteers with the Hoosier Hikers Council and the American Hiking Society constructed the new Woodlands Trail to replace a portion on the east side of the reservoir that borrowed a road. Throughout 1998 and 2001 the HHC constructed the 11-mile Wolf Creek Trail on the western half of the lake, which completed the 25-mile loop in place today."

Note that the FKT route excludes the short lollipop stick of the Midway Trail on the west side of the lake. Also, on the east side of the lake, the FKT route uses the soft-surface Woodland Trail instead of the paved Scenic Trail alternative.
It appears to start at the Midway trailhead. Is it a clockwise or counterclockwise loop after the stem of the lollipop?
Either direction. Go the faster way!
