Amy Robach, 45, and T.J. Holmes, 50, have been running in each other's minds, literally. They were spotted on Saturday, sweating it out as they took on the United Airlines NYC Half Marathon together. The event saw nearly 25,000 runners taking part in the 13.1-mile long-distance race, which works its way through the Brooklyn Bridge, FDR Drive, Times Square, and ends in Central Park.
