The blue line on the streets of New York marks the path through the five boroughs that 250,000 marathon runners traverse before reaching their goal in Central Park after 26 miles. Max, who lives in the contradiction between being a successful architect today and a political activist back then, has set himself a goal of finishing in under four hours. During the race, the past becomes present again. In this novel, which straddles the line between fiction and literary appropriation, the biography of a generation is depicted.
