Start out at Harney Rd in Scarsdale(Eastchester) and run along the little path which runs by the river uand crosses it a few times over small bridges. The tall trees provide shade durring most of the run. You must share the raod with bicycle riders so be alert. At Crestwood, cross the road and bear left a little. At this point the river widens and you should be alert for Canadian Geese. This is a beautiful and tranquil run, and a great change of pace from the track.
