Frequently Asked Questions

What if I don’t reach my fundraising minimum?

If you do not reach your fundraising minimum by the deadline, CRI will charge the balance to the credit card indicated on your registration form.

What if I cannot participate after I register?

Every team member who officially registers and obtains an entry through Team CRI is committed to reaching their fundraising minimum by the deadline regardless of any situations that may arise.
