The “40 DAYS” documentary title is derived from the grueling preparation for a prizefight that requires roughly eight weeks of Monday-Friday intense training. The first edition of “40 DAYS” spotlights the build-up to the highly anticipated Cinco de Mayo weekend matchup between Canelo Alvarez and Daniel Jacobs. Executive Produced by LeBron James and Maverick Carter, in association with DAZN and Golden Boy.
