If you are into running, you might want to check out the Better Business Bureau’s warning about a number of 5k and 10k races that may not be on the up and up.

The organization has received 47 complaints from participants who paid their entry fee, but the race got cancelled and they weren’t given a refund.

The fun runs people complained about include: the Dirty Girl Mud Run, 5K Foam Fest, Electric Foam 5K, and Color Mania 5K.
