Difficult things we do immediately; impossible tasks just take a little longer.

After running over 15,000 miles and more than 140 races, including 40 full and half marathons, all after age 55, the impossible became possible for a former overweight, out-of-shape, 33-year smoker who ran his first 26.2-mile full marathon at age 57.

From his early life growing up in rural Pennsylvania as the oldest of seven children, through a life-long career as an advertising agency executive, to eventually becoming an avid runner, Art Zimmerman's personal life journey will inspire and encourage runners and nonrunners alike to reach beyond their own expectations and self-imposed limits.

Through the eyes of an addicted, late-in-life runner, Run for Your Life chronicles how difficult challenges can be overcome with enough motivation, dedication, and perseverance-like running a marathon, even at age 72.
