LOCATION: Jug End State Reservation, 120 Jug End Road, Egremont, MA (If you type in Guilded Hollow Road, it seems you will have better luck finding the parking lot. There will be a sign at the end of the parking lot that connects out to Jug End Road though.)

COURSE DESCRIPTION: 4.2 mile course through woods, fields, apple orchard. Approximately 2.1 miles of uphill and 2.1 miles of downhill per lap. 830' elevation change per lap. Follow the Jug End Loop Trail and includes upper loop.**UPDATED Route Description**: At 5:00:00, the route to the upper loop remains open, but no partial laps will count. We will also open a .75 mile mini loop to use for the last 60 minutes. My hope is this will allow folks to get the necessary distance to hit milestones (1/2 marathon, marathon, 50k).
