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.

Here are the ways to get your bib number and t-shirt before race day:

  1. Join a Team of 12 or more!  Team captains get lots of perks, and team members get all bibs and t-shirts shipped to the Team Captains so you get yours before anyone else during the first week of March.
  2. Non-team members can get their bibs and t-shirts at the Shamrock Run Fitness Fair, presented by Moda Health, in Exhibit Hall A/A1 at the Oregon Convention Center.  For runners, your timing chip is attached to the back of your bib number.
  3. Have a friend pick-up your bib for you at the Shamrock Fitness Fair (non team members only). If you need a friend or family member to pick up your bib, please be sure you have:
