Great Cycle Challenge, benefiting Children's Cancer Research Fund, started in 2015, and after 10 years, the event has grown to become one of the biggest cycling events in the United States.

People of all ages, abilities and from every state across the country set themselves a personal riding goal and challenge themselves to pedal to fight kids’ cancer. This year the challenge will take place throughout the month of September. 

In 10 years, our community of riders from all 50 states has ridden a total of 33,817,103 miles, and together we’ve raised $72,646,876 in support of research to develop better treatments and find a cure for childhood cancer.

Why? Because over 15,700 American children are diagnosed with cancer every year, and sadly, 38 children die every week.

We're riding to give these kids the brighter futures they deserve, and we believe that any one individual can make their personal impact to fight cancer and save little lives...

So we’re calling on all Americans to get on their bikes this September and join our movement to kick cancer’s butt!

Great Cycle Challenge USA is a national Children's Cancer Research Fund (CCRF) fundraising initiative held throughout September.
