The next N24HC is scheduled for August 7-8, 2021!

COVID-19 NOTICE: The State of Michigan is currently restricting the number of people indoors to 25 and outdoors to 300, which would make it impossible for us to hold the event. Thornapple Kellogg Schools are not allowing any organizations to use their facilities at this time, and it would be impossible for us to find a suitable facility for holding the National 24 Hour Challenge in the Middleville area. Though the event is currently scheduled for August 7-8, we will continue to monitor the situation.

REFUND POLICY: If we are forced to reschedule or cancel the event this year, we will contact everyone who has registered and you will have the option of rolling over your registration until next year or receiving a full refund. Thank you for your understanding as we work through these challenges to make the crucial decisions that will result in a safe event for everyone – riders, crews, volunteers, and spectators.
