There are plenty of "tracks" around the complex, the intramural track, Girard Park is not very far from there.
I think what foofoo meant was the ability to run on a regulation track (400 yards). I used to do interval training on that track before I moved away. They have locked it on occasion, but this is the first I have heard of it.
To be really honest, the public should probably never have been able to use it anyway. Heck, you can't even go to a high school and use their track, so why would a university be any different.
