Douglas Booth and Billy Crudup have signed on to star in the sports drama Life at These Speeds.  The story centers on “a rural teenager (Booth) who loses his best friends in a tragic accident and channels his survivor’s guilt into an addiction to running, becoming a world-class distance runner in the process.”   More than a decade after portraying famed long-distance runner Steve Prefontaine in Without Limits, Crudup will return to the track world to play Booth’s coach and confidante.  Leif Tilden will direct Life at These Speeds from a script by Marc Novak, adapted from the novel of the same  name by Jeremy Jackson.  Sam Rockwell is executive producing alongside Scott William Alvarez and Peter Holden.  Hit the jump for a synopsis of the book.
