Being born and raised in San Francisco, Im often sarcastically asked how the riding is in Philadelphia. Valley Forge Nat'l Hist. Park is about an hour spin from downtown Philadelphia and as you can see from the photos it is absolutely beautiful! I have a couple of nice loops that I do out here when Im training hard during the race season. The roads are very smooth and tend to be pretty empty. While I do miss the west coast, as you can see from the photos Im not doing too bad out here.
