A few friends and I participated int eh Color Run this year. It was a lot of fun, but not my favorite 5k of the year. I wish that they had more color stations and people just throwing color packets on people along the way. I think that I am just more into obstacle 5ks. That being said, this is a great one for people who don't like mud or want to include children under 14.
You start out all white, clean, and pretty.
