Riders have been coming to West Michigan since 1982 to accept the Challenge. Here’s what they have to say about N24HC:

So well organized, volunteers are the best. You feel safe on the night loop with police at most intersections, turns have lights/glow sticks and other riders to keep you company. You get to know regular volunteers and returning riders. Just do it!
Barb Hart11-Time Rider, Michigan
When the sun rises and the last seconds tick down, you look at your mileage and hug with pride everyone who helped you reach your goal. That’s how you find what you are made of.
Matt WhiteFirst-Time Rider, New Mexico
For years, my brothers rode the N24HC, but I never went. UNTIL I was talked into it for 2007, the 25th anniversary. 257.8 miles later, I was hooked. Since then, I’ve only missed one year. It’s our family vacation!
Sarah Weis12-Time Rider, Massachusetts
Once you see the eastern sky starting to turn gray around 5:00am and hear the song birds invite the dawn and you know you only have 3 more hours to get as many miles as you can... This ride gets into your blood and it is a thing of beauty!
Randall Bertrand19-Time Rider, Michigan
It is more than a challenge to do your personal best! It is an event, and it is FAMILY. Come once, experience it, and you’ll make it a yearly ‘must do’!!
