On Saturday, I got together with some friends and we participated in the Color Run in San Francisco. It's a crazy, fun event where you run (or walk) a 5K and they have color stations set up along the route where volunteers throw colored corn starch at you.
By the end of the race you are covered in color.
There was a fun post-race party with color being thrown everywhere. Lots of fun!! We are planning on doing it again next year.
