In Portland, I stayed at Residence Inn Downtown/Riverplace, just off the I 5, right on the Willamette River. Weather was decent and I went for an early morning run along the river front.
From the hotel, I went North, following the river, under the Hawthorne Bridge, Morrison Bridge, Burnside Bridge and then I crossed to the East side of the river on the Steel Bridge. For some reason, my GPS does not seem to be synchronized with the map and shows me as walking over the water to the other side and back. Rest assured that I actually went over the bridge. I am guessing that all that steel interfered with the GPS signal. Once on the other side, I run South past the East side of the Burnside Bridge and then pretty much took the exact same route back. Had I planned this a bit better, I could have probably run in a circle or something. I generally do not like to go back and forth the same way, but this is how it worked out this time.
Generally, this is a pleasant run, nice scenery, river views. There was some noise from traffic, but not too bad. If you are ever in Portland, you cannot go wrong with this route.
