Works well to park at William Penn Park. Head north on Canyon Drive, passing by the college, and hop onto dirt for a bit. Peel off at Philadelphia Street and jog over to the trailhead via Finngal, Hadley, Alta, Broadway, Alta and Beverly. It's an easy two-mile warm-up.
Route that works well with this parking spot: Head up the canyon and climb up Sumac and Skyline. Hit up the 7th Street Loop counterclockwise. Drop Rattlesnake and climb Escalator. Cross Turnbull, ride up and over Workman Hill and descend the Cow Trail. From the bottom of the Cow Trail, follow the trail out of the canyon and back to William Penn Park. Stats: 12.5 miles with 2,300 feet of elevation gain.
If you want more, you can climb up Workman Ridge and get in a 2nd run down the Cow Trail before heading out of the canyon back to your car.
Rode this route last Sunday. First time I've ridden there since the Orange Grove access was closed off. The new (to me) pinch points on the 7th Street switchbacks seem like a good idea, although you can see that bikers and/or hikers are already creating paths around them. The east side descent on that loop is much less of a braided mess than it used to be. Rattlesnake was really overgrown. PO was really encroaching on the steepest pitch of Escalator right before the road crossing. The Cow Trail was in fantastic shape, probably the best I've ever seen.
