What is The Dirty U?

From the moment you step on the course, you will certainly notice an Oregon State  element to The Dirty U. Everywhere you turn you will see Oregon Beaver  fanatics dressed head-to-toe in their most outrageous Beaver gear!

What to Expect:

Ever wanted to look like a Beaver?   Here’s your chance.  There will be multiple “beaver stations” along the 3.1 mile course.  Beaver stations include:

Confetti Station: Black and Orange confetti of course.

Four Color Explosion Stations:  Only black and orange  (Made in the USA, High Quality, Vibrant Colors, Designed Not to Stain, 100% Safe and Non-Toxic, Biodegradable).

Grand Finale:  We will see you at the finish line!


Start the fun as fast or as slow as you want. Run, walk, or crawl through our course and school pride color stations—experience it all at The Dirty U. Don’t be surprised if at ANY point along the course you are suddenly smattered with black and orange color bombs or showered with confetti . It’s been known to get a little dirty on The Dirty U trail, so be sure to dress appropriately. WHITE SHIRTS HIGHLY RECOMMENDED!

There will be a water station at the half way point on the course—gotta stay hydrated! We will also have a delicious spread for you Beaver fans at our finish line.  By delicious spread we mean doughnut holes, mini bagels, chocolate milk, Cosmos Creations and more; did you really think we meant filet mignon?

We can’t tell you all of our DIRTY little secrets, but we can promise you will get a little dirty and a whole lot of colored (black and orange obviously). You’ll just have to show up and see what else we have in store for Oregon’s only Beaver fan 5K!  Remember, what happens at The Dirty U, stays at The Dirty U…Shhh.
