A personal-best, on-road bicycle ride to test endurance and determination.
The National 24-Hour Challenge is the largest event of its kind in the world. Each year, riders from over 20 states participate. Since its inception, cyclists have entered from 47 of the 50 states, as well as Australia, Canada, Denmark, England, France, New Zealand, Poland, Sweden, and Switzerland.
The N24HC has been held every Father's Day Weekend since 1983.
N24HC has always held that, for safety's sake, our riders must not use headphones, ear buds, etc. We want you to be constantly aware of your riding environment and we want to present a responsible image to the general public. Our 2015 Rules read as follows: "Headphones or ear buds may NOT be used when riding. Both ears must remain unobstructed."
A rider has asked for a ruling on a product, the Cardo BK-1, which allows two-way communication via Bluetooth while not blocking the ears. Speakers are mounted to the helmet, not the ears, leaving a space – typically one inch – which allows for normal hearing.
This product, and others like it, WILL BE ALLOWED at the N24HC. We reserve the right, as always, to disqualify riders who present a danger to themselves or others.
Please note that we have not relaxed our cell phone restrictions. Distracted riding is as bad as distracted driving.
- Riders may use the Cardo for communication with crews and other riders within range of the Bluetooth signal.
- Riders may NOT use the Cardo for cell phone communication while riding.

2015 Volunteer of the Year
Jay passed away Wednesday evening, 6 May 2015.
Jay grew up in Detroit, and after visiting his relatives in Germany, brought home his bride, Lene. He was always an active athlete, in speed skating, swimming, running, and biking. Jay rode seventeen 24-hour endurance events on Belle Isle.
On moving to Middleville, Jay was drawn to our event, the National 24-Hour Challenge, which originated in 1983. Jay painted our route arrows for 26 years, from 1989 through 2015. While tending the arrows on our three-loop, 155-mile course, he also filled potholes and suggested route improvements - Jay was always there for us.
Jay rode the N24HC for 15 of those years, setting a personal best of 355 miles in 1997. In 2014, at age 72, he rode 278.3 miles. He joined our Board of Directors in 2011.
Jay had planned to ride this year, but his training was brought to a halt by brain cancer. We will remember Jay as a fine gentleman and a devoted athlete. We are privileged to have known and worked with him.
It's the 2015 t-shirt design!
