There are no personal bests at the Color Run, a 5k held in Seattle Sunday morning. Race officials don't even time the event, instead focusing on having fun, that and lots and lots of colored cornstarch.
Runners start the race dressed all in white, like brand new blank canvases. Throughout the run they get "painted" at color stations. I showed up in time for the race after party, where any blank canvas got thoroughly covered.
The clean up station was a guy with a leaf blower.
