The Better Business Bureau of Minnesota is advising people to be cautious when signing up for themed races, also known as “fun runs.” They say, while most go off without a hitch, but a handful have been rescheduled, postponed or even canceled. The problem is that often, when you sign up, there are no refunds or there’s a no-refund policy. They suggest checking and looking at customer reviews. Ddon’t be fooled by a fancy website. Confirm with the local venue that the event is on, and pay by credit card.
