Seattle Cherry Blossom Run

Sat March 25 - Sun March 26



University of Washington, Seattle, Washington, USA!


The much anticipated Seattle Cherry Blossom Run is ready for you to celebrate spring at the University of Washington campus this March 25th and 26th, 2023! 

Sign up to be a part of the Legion of Bloom! Just choose a 5K Run, Half Marathon or Sip n' Stroll 5K and we will run, walk, stroll or crawl our way through campus enjoying a variety of cherry blossoms.

Finish near the famous 29 yoshino cherry blossoms that exist the UW Quad! As many already know, these are some of the most beautiful and mesmerizing blossoms you'll ever see in the west!

For those running virtually, you'll have until the end of April to run and experience cherry blossoms from wherever you are! Virtual run kits include shipping and we'll mail then out beginning mid March!

Follow us on Facebook and Instagram and hashtag us in your amazing event photos and video.
