Olympic silver medallist Michael Jamieson was also at the British Swimming Heroes event at the Gurnell leisure centre in Ealing.
He told Emma Walden that it was an exciting time to be involved in the sport.
Rebecca Adlington spoke to our reporter Emma Walden at an event designed to inspire the next generation of Olympic swimmers.
She said that working with kids was one of the best parts of her job as an elite athlete.
Stars of the 2012 Olympics gathered at an Ealing swimming pool this morning to help get children interested in water based sports.
The Britsh Swimming Heroes Tour includes members of the swimming, diving, water polo and synchronised swimming teams.
Emma Walden went to meet them and sent this report from Gurnell Leisure Centre.
Londoner Daniel Fogg is the the only British male swimmer to compete in the 10km open-water event. If that was not enough, he is also competing in the 1500m event in the pool.
British swimmer Roberto Pavoni from Brentwood in Essex picked up his Olympic training kit and knows that he has to make a quick start once the Games begin.
Swimming in the Thames in London is to be banned from Sunday.
A new bylaw makes it an offence to swim in the river between Crossness, near the Thames Barrier, and Putney Bridge without written permission of the Port of London Authority.
It is being introduced after interest in “wild swimming” in rivers surged following comedian David Walliams’s 140-mile charity swim of 140 miles of the Thames in eight days last year.
A spokesman for the authority, which is responsible for the tidal part of the river, said:
"Often the result is tragic. It’s not just the swimmer’s life at risk. If a boat spots a swimmer in the water and has to take evasive action, other lives could be at risk.
“The Thames is getting busier with commercial traffic and increasing numbers of leisure boats.
It is not the place for swimming.”
The Environment Agency, responsible for the Thames from west London upstream, said it was not introducing an outright ban but warned “the Thames is not a swimming pool”.
Hundreds of London's school children were centre stage at the Aquatics Centre this afternoon as they came together for the first community event at the prime Olympic location. It's given them all a taste of things to come after the 2012 Games.
Hundreds of London school children joined in for the Six Host Borough Swimming Championships in the Aquatics Centre. It's the first community event in the Aquatics Centre put on by the Legacy Company.
The Legacy Company have said that this will be a community facility after the Games. They say it will be affordable and accessible with 90% of its use for the community and the price of a swim the same as the average price for a swim in other nearby pools.
