This was the only edition of the Short Course World Championships that Michael Phelps competed in.[1] Phelps planned to swim in six races: the 200-meter freestyle, 200-meter butterfly, the individual medleys at 100 meters, 200 meters, and 400 meters, and the 4x200-meter freestyle relay.[2] Phelps won gold in the 200-meter freestyle on October 7 - the only Short Course World Championships gold medal (and medal of any color) of his career - then withdrew from the rest of the meet the following day, citing a sore back.[3]
