Finally got full info on the "Big Boy" loop at Loch Raven. Starting at Seminary and hitting both singletrack loops on the left. Through Sam's up the first major climb. To the green gate on LR Drive and across bridge and left up 2nd major climb. Take gravel downhill to 3rd and most difficult climb and down to Glen Arm and around Cromwell to LR Drive and back up to fireroad. Take fireroad to Providence and cross over to fireroad and up through Log trail and take fireroad to singletrack to the left and dumps back onto the foreroad and back to Seminary. Great ride in the Ferrous rigid SS w/32/18.
