The Shamrock Run is one of the biggest races in Portland and happens on the Sunday nearest St. Patrick's Day.  There are three races, a 5K and 8K around downtown, both of which are relatively flat, and a 15K which runs up the West Hills and back down.  It's basically a 9.6 mile run with a 70-story building thrown in the middle for good measure.

Beth and I both ran and both finished, Beth about 5 minutes faster than me.  I took a selfie every mile of the entire race.  Enjoy!
