Want to bring a first-time rider to the National 24 Hour Challenge this year? If you do, the first-time rider can get a discount and you can get a free water bottle or hat for bringing them to the National 24 Hour Challenge – but both you and the first-time rider must register no later than June 30th. See page 6 of the Rider Information Packet for more details!
This year, all registrations must be made through register.24hr.bike. Registration closes at 6 p.m. EDT on Friday, August 6, 2021.
We are asking all riders who rolled over their registration from 2020 to visit register.24hr.bike to verify your information and make sure we have the correct information for you.
We encourage anyone who wants Support Team services to register soon as we have a limited number of openings and the Support Team services will sell-out.
Some riders have reported that our registration website emails are delivered to their spam folder and not their inbox. When you are registering for the National 24 Hour Challenge on register.24hr.bike you will receive your registration link and registration confirmations emails within 15 seconds. If you do not receive them – check your spam folder. If they are not in your spam folder, please contact us.
