Is Katie Holmes
back on the treadmill for another big city marathon? Not so, according to her rep. Rumors were flying this week that Holmes, who ran the New York City Marathon
in November, had signed up for the Boston Marathon. But her publicist tells PEOPLE: "Not true!" For now, it appears Holmes, 29, will stick to jogging up and down the red carpet.
