The New York City Marathon is here! Bill is in The Big Apple to raise funds for breast cancer awareness and Giuliana's charity Fab-U-Wish. But between jet lag and his excitement, Bill steps to the starting line already low on energy. Meanwhile, G takes her parents on a three-day longevity workshop to teach them to be more health-conscious. Will the lessons take? Then, the family reunites in D.C., where Giuliana's dad is opening a new store! See if Bill can muster up the strength to attend just hours after running 26.2 miles. Plus, will surrogate Delphine agree to carry the Rancics' second child?
