Event Cancellation or Reschedule Policy
Race organizers reserve the right to cancel the event in the case of COVID, extended severe weather or other emergency. We will do everything possible to get the event in, but refunds are not available if it is cancelled or rescheduled due to significant costs we must pay in advance of the race (e.g., insurance, permits, vendor deposits, advertising, graphic design, etc.) along with hundreds of hours of planning. If it is cancelled or you cannot attend on the rescheduled date, we will provide a generous credit (the amount determined by the financial impact on the long-term health of the race) that can be used for Coast to Coast Gravel Grinder, Lord of the Springs or any Michigan Adventure Race in the TWO years following the race year. ending Dec. 31 of the second full year.

In the event of a thunderstorm, we will postpone the race until conditions improve. Extended severe weather may result in cancellation of the event.
