Up Sheltowee Trail to Lakeview Trail and make a right. The loop starts at this intersection. Stay on trail until end of big downhill. Ride across wooden bridge and get on double track to pavement. Turn left and ride on paved road about 1/2 mile. Turn left on USGS gravel road (I think it is FS 16). Long, beautiful climb. Turn left onto FS 964. I usually stop at Amburgy Rock and hike up to top of rock and check out view from highest spot around. Back on bike, ride til road turns to doubletrack. Expect some wet/mud on the double. Then hit Big Limestone (Trail 109) for a big time. "Three witches" climbs will keep you honest. Left turn back onto Sheltowee for "all DH from here" finish. You will hit the intersection of Lakeview and continue DH to the car. Huge descent with exposure to the right, then left on this ending DH.
Total gain was 1810'. About 360' on the initial climb on the lollipop stick to the loop and about 1450' on the loop.
I'd say about 1/2 mile paved, 6-7 miles of gravel/double and 8-9 miles of singletrack. Absolute quality ride in a beautiful forest.
Map to follow when I get home and can get it off my GPS.
