The Cinco de Mayo Run kicks off in Portland’s scenic Sellwood Riverfront Park, where runners can take in views of the Willamette River, tree-lined paths, and the city’s lively spring atmosphere. Offering a Half Marathon, 10K, and 5K, the course blends urban charm with riverside beauty. Finishers are greeted with warm, cheesy quesadillas—because every great run deserves a delicious fiesta at the finish line!
