What exactly is the Battle of Champions?

The Battle of Champions is the final round for the FINA World Championships.  All athletes that complete either the Speed or Endurance Course will be seeded into a bracket-style competition.  Athletes will race in a one of a kind, head-to-head course combining the greatest elements from the Speed and the Endurance course. The races will continue until one athlete remains, and that athlete will be crowned FINA All-Around Champion.
