Portland to Host Rebranded Shamrock Half Marathon Run Fest

Mar 13, 2025

From 2025, the Shamrock Run in Portland, Oregon, is rebranding to the Shamrock Half Marathon Run Fest presented by Toyota. Returning to the downtown waterfront on the weekend of March 14-16, 2025, the St Patrick’s Day-themed event will also introduce changes to its race format, promising an enhanced experience for both runners and festival goers alike.
 

One of the most notable changes is the combination of the 15K and 13.1-mile distances into a single, half marathon event. According to the organising team, this new format will provide runners with a wide-open, dedicated course and an earlier start time, optimizing race conditions and logistics.
 

The refreshed format will debut the official ‘Terwilliger Challenge’, a race-within-the-race competition celebrating the fastest athletes to conquer the event’s signature climb.
 

“We’re thrilled to introduce the Terwilliger Challenge as a new element of the half-marathon,” said Alex Jee, Community Manager for the Shamrock Run Fest. “Along with the change to Shamrock Run Fest and the introduction of an exclusive half-marathon course, it really allows us to focus on delivering a first-class running experience for all of our participants and teams, while also better showcasing the Shamrock Showdown.”
 

The Shamrock Showdown 8K, a competitive highlight of the event, will aim to be bigger and faster in 2025. With prize money and team competitions, the 8K annually attracts some of the fastest elite runners from the Pacific Northwest and beyond. The separation of the half-marathon and 8K finish times will help to ensure the proper attention and recognition for each race, showcasing the top athletes and adding to the event’s prestige.
 

“The Shamrock Showdown continues to grow in popularity each year, but previously the half-marathon and 8K winners both finished around the same time in different locations,” added Jee. “With the new format, we can highlight each separate champion with our announcer and more fanfare, ultimately providing a better production experience for participants and spectators at the finish line.”
 

The race weekend will again be held in partnership with Kells Irish Pub & Brewery to co-host the three-day Kells Portland Irish Festival through St Patrick’s Day Monday. Participants can look forward to a weekend filled with music, food and cultural festivities at Tom McCall Waterfront Park.
 

The Shamrock Run Fest will continue to serve as a supporter for OHSU Doernbecher Children’s Hospital. The partnership has raised more than US$835,000 for the Friends of Doernbecher Grant Program, which funds projects and cutting-edge research that directly benefit current and future Doernbecher patients and families.
 

The half marathon weekend kicks-off with the Shamrock Fitness Fair at the Oregon Convention Center on March 14-15 where participants pick up their race number. The Fitness Fair features exhibitors, running celebrities, contests and giveaways.
 

The Shamrock Run Fest offers a variety of race distances from 5k to a competitive 8k, half-marathon, as well as the Shamrock Stride walk and a children’s 1k Leprechaun Lap. Race day culminates with a finish line festival at Waterfront Park, featuring a beer garden and an entertainment stage with performances from local musicians.
