I'm a runner and I occasionally enter a few races. One in particular that I've thought about is the Color Run. It looks like fun but I was wondering how my piece would hold up. The Color Run is a paint race where runners are literally covered head to toe with this colored powder as they're running. Does anyone have any insight on the effects it would have on a piece?

Here is link to a video for the color run:
