I didn't take too many photos, due to all the dye dust in the air, but this is one of several I shot at a recent race in Nashville, TN. As folks ran the 5K course, volunteers through handfuls of powdered dye on the participants. It was a very messy race.
I shot this with my little Fuji X100S. It did a great job and it was easy to keep it covered from dye debris.
