Every journey starts with a first step. Your journey starts now.
You’ve been here before and can’t wait for June.
This year, explore your limits at the National 24-Hour Challenge – the oldest and largest ultramarathon cycling event in the nation. Come to beautiful West Michigan and test yourself in the company of 400 riders. The N24HC is your opportunity to find out what you can do.
The National 24-Hour Challenge is a personal-best on-road bicycle ride to test your endurance and determination. N24HC has been held every Father’s Day Weekend since 1983, with riders coming from all over North America, as well as Europe, South America, Asia and beyond.
The event is officially a 24-hour Challenge, not a 24-hour race, because it’s all about personal accomplishment and discovery – a place to break through what you thought were your limits. That said, we do recognize riders’ incredible accomplishments with award categories broken down by age, sex, and bicycle type, as well as family categories. And thousand-mile jerseys for multiple-time participants!
Whether your goal is to see if you can make it around the 120-mile daytime loop, smash the course record, or just have a fun ride with 400 of your closest friends, the National 24-Hour Challenge is the place to be in June!
