Top Olympic swimmer Ian Thorpe gets back to training

Swimmer and five-times Olympic gold medallist Ian Thorpe is back in the pool.

He's set his sights on competing the London Olympics 2012, ending his four-year retirement.

The Australian's known as the "Thorpedo" because he's so fast in the pool.

He won his golds at the Olympics in both Sydney and Athens and is now ready for a comeback.

After visiting the Olympic swimming venue in London he said it renewed his love for the sport.

He's now working on his freestyle at a secret base in Switzerland.
