Ride slab after slab on one of South Rutherford's most acclaimed downhill runs, Upper PHD.
This double black diamond of a ride has a pucker factor that exceeds any other trail around and to make it even more rowdy, narrow lines between the slabs make it hard to keep your flow.
Scout any feature prior to riding and consider saving this ride for the driest of conditions.
Upper PHD is accessed from the top of the South Rutherford Access Road and ends further down the road.
Continue onto Middle PHD if you don't want the fun to end! [Source](https://www.youtube.com/watch?v=HHyTwKfosaI)
