You asked for it and we were able to make it happen this year!
More roads and much less use of the multiuse paths!
You will be riding on the roads in Valley Forge National Historic Park, except where one way roads make it impossible. You can ride on North Outer Line Drive, North Inner Line Dr., Valley Creek Rd., Valley Park Rd, and Valley Forge Rd.
You will need to use the path to leave the rest stop for the Chester County Extension Loop and to return to the rest stop before leaving the park to return to Philadelphia. Both are short distances compared to what you did in past years.
When you see the folks at Valley Forge, thank them.
As always ride carefully and with courtsey, these are narrow, busy roads that we need to share well.
