Register by September 1, 2023 to guarantee your shirt size/availability. Online registration is open until midnight EDT, October 1, 2023, or when capacity is reached, which ever comes first. There will also be day of on-site registration during the event.

You can change distances prior to online registration closing by editing your current registration before October 1, 2023 or on site during check-in.

If the race is canceled for any reason (such as, but not limited to: flooding; state or federal closures; local authorities having jurisdiction; permitting, insurance or sanctioning revocation), the race will be run virtually. If this happens, specific details will be emailed to all entrants. Please plan accordingly. No refunds, transfers, rollovers or deferrals will be given in the case of the race moving to a virtual format. Swag/finisher’s awards will be mailed. If necessary, shipping outside the USA will incur additional charges.
Refund/Cancellation Policy:
We do not provide refunds, deferments, rollover credits, transfer of entry fees, etc. This includes if the event is postponed or canceled for any reason. Selling/giving your bib to someone else is not permitted. If you would like to potentially be reimbursed if you are not able to participate or the event is postponed/canceled, we recommend you consider purchasing event registration insurance to cover yourself. We do not provide this service. More details are available on this website here. Please read it carefully with understanding before registering. Don’t register unless you understand and agree to this policy. Thank you!
