CBS Biography
These comic book aficionados are determined to be the most strategic team ever to compete in the Race. Mark and Bill, friends for over 23 years, first met at a science fiction club and have been bonding over their love for comics and games ever since. Mark says that he “wears geek like a badge of honor.”

Mark describes himself as outgoing, funny and smart. He is willing to go anywhere and isn’t afraid of adventure. His last vacation was to Vanuatu in the South Pacific where he climbed a volcano.

Bill is the opposite of Mark -- he describes himself as cautious, easygoing, goofy, yet competitive. When asked how the Race could change their friendship, Bill says that the Race might present them with some bad situations, but in the end, they’ll finish with a deeper respect for one another.

These masterminds are ready to see what they are made of and are convinced that they can be one step ahead of the competition if they play their cards right.
