Privacy Violation - HELP!

We love the idea of bike to work day, but is there a way to remove the public posting of personal name and information. When we signed up we did not know it was going to post our personal information so anyone doing a google search could find out our name, city where we live and where we bike. We are very private and area already dealing with phishing, spam and internet harrassment and don't need Bike to Work day publishing name and other information to add insult to injury. How do we opt out of this? Who do I contact to have public personal posting and privacy violations removed?
