Decision-making authority to proceed or cancel the race based on weather conditions rests almost solely with Maryland Transportation Authority. A cancellation could arise over a "likely" forecast of inclement weather. During Inclement weather, the MDTA does not implement two-way operations on the Bay Bridge's westbound span. As such, the eastbound span cannot close for the event and the race would be cancelled.
Public notification of the decision to cancel can be made as late at 5 a.m. on the day of the race.
