Shamrock run information


Founded in 1979, the adidas Shamrock Run is the largest running and walking event in Oregon and is the third largest running event in the western United States.  In 2017, 30,000 participants will celebrate the 39th edition of the event on Sunday, March 19 at Waterfront Park in downtown Portland. 

The adidas Shamrock Run offers competitive races at 5 kilometers (3.1 miles), 8 kilometers (4.97 miles), 15 kilometers (9.3 miles) and a half-marathon (13.1 miles). Shamrock also has a 4-mile fitness walk – the Shamrock Stride – and a 1km (0.6-mile) run/walk for children age 10 and younger known as the "Blazers Leprechaun Lap."

The Shamrock Half has its own field limit of 3000 runners.

All the courses start at Waterfront Park near SW Oak and Naito Parkway and run through the center of downtown Portland for a fun urban experience and feature slightly downhill final sections. The 15k and half-marathon routes include the challenging, and scenic,Terwilliger hills.  The new Shamrock Stride 4-mile walk boasts city views and a river walk including the Tilikum Crossing and Steel Bridges.

Shamrock Sunday activities in the finish area include the Widmer Brothers Brewing beer garden, complimentary hot soup and an entertainment stage with performances from local musicians.  Music is featured at the starting line and along the Shamrock routes.  Hours for the post-event festivities:  8 a.m. until 1:00 p.m. in Waterfront Park.

Shamrock Weekend kicks-off with the adidas Shamrock Run Fitness Fair.  This two-day event at the Oregon Convention Center on March 17 and 18 is in conjunction with Shamrock participant bib number and T-shirt pickup. The Fitness Fair features more than 80 running and fitness exhibitors, celebrities and mascots, contests and give-aways and a Leprechaun Lane area for kids. More than 25,000 people attend the Shamrock Fitness Fair.

All adidas Shamrock Run participants receive the following:

  • A souvenir Shamrock short-sleeve poly blend runner's style T-shirt;
  • A pour of Widmer Brothers beer (for those over 21);
  • A 6-ounce serving of Shamrock Irish Potato soup made from Pacific Foods products; and
  • A commemorative bottle-opener medallion (for 15km and half-marathon finishers only).

The adidas Shamrock Run offers a reduced entry fee for members of teams with 12 or more participants and special perks for Team Captains. This entry fee incentive has resulted in the registration of more than 500 company, neighborhood or special interest teams, and has contributed significantly to the tremendous growth of the event, which has tripled in size since 2008.

The adidas Shamrock Run is sponsored by adidas, Widmer Brothers Brewing, OHSU Sports Medicine, Moda, Portland Trailblazers and Pacific Foods.  The primary beneficiary of the event is Doernbecher Children's Hospital Foundation, which has been affiliated with Shamrock for the past 20 years.
