Shamrock Run Portland

Founded in 1979, the adidas Shamrock Run Portland is the largest running and walking event in Oregon and is the third largest running event in the western United States. In 2018, 30,000 participants will celebrate the 40th edition of the event on Sunday, March 18 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) with a field limit of 3000 runners. Shamrock also offers the Shamrock Stride – a 4-mile fitness walk – and the “Blazers Leprechaun Lap,” a 1km (0.6-mile) run/walk for children age 10 and younger.

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 16 and 17 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, presented by Moda Health.

The adidas Shamrock Run is sponsored by adidas, Widmer Brothers Brewing, Moda Health, Bob’s Red Mill, GEICO, nuun hydration, iHeart radio and KGW Newschannel 8. The primary beneficiary of the event is Doernbecher Children’s Hospital Foundation, which has been affiliated with Shamrock for the past 21 years.
