Welcome to 24 HRS of Cumming!

This gritty bike race will take place entirely on the gravel roads of central Iowa. It will be one of the toughest endurance biking challenges in the United States. Riders will have 24 hours to cover 400k (that's 248 miles to you and me) and nearly 15,000 feet of elevation gain. That's a challenge for even the gnarliest of grinders! We also offer a 100k solo and NEW this year will be a 200k solo! Not ready to tackle this beast solo? Take it on with a team of 2 or 4 people. To keep this beast from getting out of hand we will cap each race so register now!
