Swim4Life participating pools are being pumped pounds to provide pay-free plashing but also to improve their premises so there's some kind of payoff for us post-adolescent, pre-pensioner peoples who still have to pay. There's no guarantee the scheme will last beyond 2011 though, despite DCMS's aspirations for an Olympic legacy of free swimming for all - which has been watered down to a vaguely achievable "2 million people more active" by 2012 - so piddlers and pensioners make like porpoises while you can.
