AboutGreat Cycle Challenge USA encourages riders across the United States to challenge themselves and set their own personal riding goal throughout June to fight kids' cancer!

It doesn't matter if your challenge is to ride 15 miles or 1,500 miles throughout the month, the event is all about setting your own personal goal, getting fit and riding to end childhood cancer.

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

Well, we're riding to change that!

You can log your miles via our FREE app, Strava, MapMyFitness/Ride/Run, your own personal GPS device or simply add them manually to your rider dashboard!

We'll give you your own personal rider page which you can personalize, track your progress and ask your friends to support your challenge.

You can ride solo or create a team with your cycle club, friends or workplace - it's up to you.
