Cinco de Mayo

Get ready to experience the vibrant Cinco de Mayo race, taking place on Sunday, May 3, 2026, in beautiful Portland, Oregon. This beloved spring event in the Northwest offers a fantastic blend of urban charm and riverside beauty, making it a highly anticipated run. Participants can choose from a variety of distances, including a Half Marathon (13.1M), 10K, 5K, and a Kids Fun Run (0.4M).

Kicking off and finishing at the scenic Sellwood Riverfront Park, runners will enjoy a mostly flat and fast course along the Springwater Corridor trail, known for its paved and smooth terrain. This ideal course is perfect for chasing a personal best, with pleasant typical race day conditions in early May featuring highs around 67°F and lows around 47°F, and only a 10% chance of precipitation. The race is well-regarded for its excellent organization and engaging, fiesta-like atmosphere, with one runner praising the "Great course that was clean and well maintained with so many wonderful volunteers!". Aid stations are strategically placed approximately every 2-3 miles along the Half Marathon and 10K routes, fully stocked with water, electrolytes, GU gels, and gummy bear chews, along with portable toilets.

What truly sets the Cinco de Mayo race apart is the lively celebration that awaits participants at the finish line. Runners are greeted with warm, cheesy quesadillas to refuel and commemorate their accomplishment, adding to the festive ambiance. Organized by Negative Split, this event promises a fun, scenic, and well-supported experience for all.
