I need to get some pictures. I have 2 favorite spots depending on my mood--one is FLAT the other HILLY. the hilly one is exactly a 5k loop around a lake with about a mile of trail and the rest paved with some serious hills. its a nature preserve/park and is gorgeous. the other is a flat paved trail that starts on the island in the middle of the susquehanna river here--then you go across the bridge and you run up along the river for about a total of 3.5 miles or so (so down and back if you do the entire thing will get you about 7 miles). its nice as the harrisbrug road runners have marked off the distances so you can do speed work etc. along the path. the bad part is on nice weekend days, unless you get there early it can get crowded with bikers, runners and walkers.
