Can you imagine running from one coast of the United States to the other? Christian McEvoy is doing just that, and it's all for a great cause. Bob talks to Christian about his incredible journey across the country, called "Coast to Coast: A Run for Survivorship."

Christian says the idea for the cross-country marathon came after his friend's mother was diagnosed with breast cancer. Looking for a way to support his friend, Christian entered a bike race for cancer survivors. He says he was inspired by the race's organizer, a man who lost his leg to bone cancer and ran across the country with only one leg.

With the help of family and friends, Christian began his own trek across the country on July 1, 2006, in San Francisco. When Bob catches up with Christian, he is in Mount Claire, New Jersey, and just 11 days away from completing the run. The trek is scheduled to end December 16 in Narragansett, Rhode Island.

Christian says the goal is to raise funds and awareness for the estimated 10 million American cancer survivors. To date, Christian and his team have raised over $170,000. Despite the hardships of running anywhere from 15 to 40 miles a day, Christian says the response from supporters has been overwhelming and deeply motivating.

"My feet are doing the work but I really feel that I'm filled with the will of cancer survivors that I've met and those I haven't met," Christian says. "They have really pushed me along and made this an easy endeavor."
