Tae Smith only started swimming lessons five months ago, for safety reasons to learn the basics, and now practices for just an hour a week. Her instructor saw her as a natural on day one, and now thought she was ready to take the 600 meters distance badge, already an impressive achievement for a four-year-old. But Tae begged to carry on, until she was persuaded to stop at 2000 meters. On July 23, she hopes to repeat the feat and set a Guinness World Record, rasing money for the Macmillan Cancer Trust.
