Renamed Shamrock Half Marathon Run Fest in 2025

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

One of the most notable changes is the combination of the 9.1 mile and 8.1 mile distances into a single half marathon event. According to the organizing team, this new format will offer runners a wide-open, dedicated course and an earlier start time, optimizing race conditions and logistics.

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

“We are excited to introduce the Terwilliger Challenge as a new element of the half marathon,” said Alex Jee, Community Manager for the Shamrock Run Fest.

“Together with the change to Shamrock Run Fest and the introduction of an exclusive half-marathon course, this really allows us to focus on delivering a first-class running experience for all our participants and teams, while also better showcasing the Shamrock Showdown. ”

The Shamrock Showdown 8K, a competitive highlight of the event, aims to be bigger and faster by 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 between the half marathon and 8km finish times will help ensure the right attention and recognition for each race, highlighting top athletes and increasing the prestige of the event.

“The Shamrock Showdown continues to grow in popularity every year, but previously the winners of the half marathon and the 8K both finished around the same time in different locations,” Jee added.

“The new format will allow us to highlight each individual champion with our announcer and more fanfare, ultimately creating a better production experience for competitors and spectators at the finish line.”

The race weekend will once again be held in partnership with Kells Irish Pub & Brewery, which will host the three-day Kells Portland Irish Festival through St. Patrick’s Day Monday. Participants can look forward to a weekend of 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 $835,000 for the Friends of Doernbecher Grant Program, which funds projects and groundbreaking research that directly benefits 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 and 15, where participants will pick up their bibs. The Fitness Fair features exhibitors, running celebrities, competitions 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 1K Leprechaun Lap for kids. Race day ends with a finish festival in Waterfront Park, featuring a beer garden and entertainment stage with performances by local musicians.
