Woven into the narrative will be supporting characters: fixtures like 65-year-old Tucker Andersen, who has run the five-borough race every year since 1976, and John Codiglia, police chief of the 10th precinct, who entertains runners with his bullhorn as he stands on Central Park South near the finish. Flashes of history will amplify the present and provide insight into the neighborhoods and the people who have made the race into the phenomenon it is today: the race's charismatic founder, Fred Lebow; Grete Waitz, the Norwegian-born runner who won it a record nine times; Vic Navarra, a retired firefighter who has directed the start in Staten Island for three decades and is dying of cancer; and, Mary Wittenberg, the chief executive of the New York Road Runners Association, who has vaulted the organisation to international prominence.
