Finisher Medal


The Shamrock 5K starts at SW Pine and Naito Parkway on the Waterfront. Runners will stay on Naito for the majority of the 5K course except for a quick excursion to Taylor –> 1st Avenue –> Salmon –> back to Naito to get that 0.1 mile in, making it a true 5K (3.1 miles). The turn-around point is on Naito, just past the Tilikum Crossing. The course ends on Naito Parkway in front of a cheering crowd at the intersection of SW Yamhill.
