Entry fees are non-refundable. Entries are non-transferable to another person. That means that once we receive and accept your entry, you will not receive a refund if you cannot participate. You may not transfer your entry to another participant, or to another year. The Marathon, in accordance with management executives, city officials and local law enforcement has the authority to cancel any of the events for emergency purposes such as, but not limited to, inclement weather or threat of terrorism. If such emergency conditions force cancellation, refunds cannot be provided since funds will have been spent in preparation for Race Day.
