I used to think The Color Run was a really cool event run by cool people. I've since found out it's run by a very sketchy guy who sued a photographer who dared to demand money for the Color Run to use the photographer's photo. They also rely on volunteers who think they are helping a charity, but actually are working for free for a "for profit company". I hope we get a call from one of these volunteers. We'll hit 'em with a class action for wage & hour violations!
For now, I'm going to support the Color Dash instead. They seem to be more open about what they do, what they give and who they are. And they don't sue you for taking pictures at their events.
