Referral Program

C4 Gran Fondo Referral Program — How It Works

1. Register yourself for the C4 Gran Fondo
   You can use someone else's referral code OR leave it blank.

2. Find your code
   Use the receipt number at the bottom of your registration confirmation email.

3. Share it with friends and family.
   Give your code to friends and family before they register.

4. Earn a Free Registration
   Once your code is used 5 times, we’ll refund your registration fee minus processing fees. Only one referral code can be used per registration.

5. Your Friends Can Earn, Too
   Anyone who registers with your code will receive their own code—and they can also earn a free registration by sharing it with others.
