The Able Baker Challenge is an unofficial spacecraft racing event held in the Baker system. It makes use of system-specific obstacles to hamper the pilots' efforts in reaching the finish line. Though the use of weapons is allowed during most legs of the race, shooting to kill is generally discouraged. Even so, the casualty rate of participants can be high. Racers are alerted to the time of the event one Standard Earth Day (SED) before it is set to begin.
