COVID-19 NOTICE: Due to the increasing number of COVID-19 cases in Michigan, the restrictions on the number of people who can gather indoors and outdoors, and school district facilities being closed to all non-school activities, the 2021 National 24 Hour Challenge has been rescheduled for the weekend of August 7-8, 2021.
We are extending the registration fee of $150 through June 30. From July 1 through July 30, the registration fee will be $170, and from August 1 through August 6 the registration fee will be $200. If you have previously registered and will be unable to participate in the National 24 Hour Challenge on August 7-8, you may roll-over your registration to 2022 or receive a full refund of your entry fee. Please email firstname.lastname@example.org if you want to roll-over your registration or receive a refund.
