From the Facebook event page:

Activate your hyper drive and get stoked for the final cycloross race of the season! Seattle’s got a lot of space related stuff, you’ll ride your bike to a bunch of it and compete in out-of-this-world bonus challenges! It’ll be great!

Bring: A Bike (any bike will do, this will be majority road riding and not actually a CX race) a phone or whatever to post photos/video for scoring, a cup for the after party because disposable plastic cups are for losers.

Riders encouraged to form a “space crew” of approximately 4

All proceeds from registration go to Plant for the Planet, worldwide youth run organization that plants trees in order to offset carbon emissions and make Earth habitable for a little bit longer. http://www.plant-for-the-planet.org/en/home
