At the stores group runs, we have been able to go back to our old "trail" run route. During the winter and darker evening runs we try to stay on sidewalks to make sure all runners are a little bit safer when running.
It has been nice to go on some of our old routes. I shouldn't call the routes old though, they haven't changed they are more like "classics". The tow path in Princeton is always a favorite for group runs when we have the opportunity to get down there.
It looks like we will see some more options for group run routes, for a while.
