I was signed up to run the Pasadena Marathon last November. It was cancelled at 4am (start time was 6:30am) due to air quality warnings from forest fires in the region. This is the first time I've experienced a race cancellation. What usually happens and what should happen in such an event?
The race organizers cited that they had already incurred much of the cost of organizing the event and did not purchase cancellation insurance. As a result, the participants were not given any refunds. They rescheduled the event and those who had originally registered will have to pay again but will get a 50% discount. I can't do the new date due to event conflict so I'm pretty much just out of luck.
I've had some arguments about the fairness of not getting any refunds. Concerts, ballgames cancel and refunds get issued. It seemed to me that feeling some entitlement to a refund isn't out of order. Others seem to accept it with a "suck it up and don't whine" attitude.
