Re: Philadelphia area runners -- Main Line, specifically
I usually run from Betzwood on the weekends. In addition to the standard directions from Rt 422, you can also get there from the Paoli side of the Schuylkill. From Paoli, take 252 North until it ends at Rt 23. Right on Rt 23 and left at the bottom of the hill. Park at the dead end and walk across the boardwalk bridge along 422.
Since a few people have expressed interest in these routes, everyone should also know that there is a 5 mile loop in the main section of Valley Forge Park and there are trails (hills, rocks) on Mt Misery and Mt Joy both of which are accessible from VF park. From the top of Mt Misery you can even catch the Horseshoe Trail which eventually ends in Hershey!
I can give more details on any of these.
The Valley Forge Striders run from Betzwood on Saturdays at 8am and from the Main VF Park on Sundays at 8am. I've never run with them but its on their website.
If you get a run together let me know, I'll try to make it.

On a tangent, I read about a fun way to run with a group of diverse speeds in Runners World. You pick a time-length of run and set off on an out-and-back course (the Schuykill trail is a good choice.) Everyone takes off at the same time and runs whatever pace they want. At the halfway (time) point, everyone turns around and races back to the start now the it is a handicapped race to the finish where you have to run a negative split in the second half to catch a slower runner or stay ahead of a faster one. My wife and I do this together and its a lot of fun.
Take Care,
