Nice place to run and bike with incredible views of the city. I prefer the wooded trail portion because I'm not running on pavement, it's easier on my knees (I'm old). Lots of places to park along the trail, like Washington's Landing and near Heinz Lofts. The scenery makes this one of my favorite running spots, but there are definitely more people on bikes than on foot. As long as you can dodge them and trust that they'll dodge you, it makes for a really wonderful workout. Where else can you run along side a submarine?
