Be in the city and the US’ largest metropolitan park, Washington Park in Portland, Oregon, at the same time, and get active on one of the best trails, the Lief Erikson. After a slight but manageable first mile incline, its mostly flat and wide open, great for running even if your not an avid trail runner. The trail floor makes running in the rain very doable and if you are a dog owner, be sure to bring fido, the trail is very dog friendly. Half mile makers along the way help keep your out and back distance in check. Visit http://trailweb.net/portland-trails-leif-erikson/ for exact location and elevation details.
