The campaign has been developed by Iris. It will break across digital, press, retail and promotional, and has positioned the website at its core.
Online and press ads directing people to the site in the UK will be supplemented by activity in France, Germany and Italy next month.
According to a company statement today (16 May), the digital campaign aims to "drive a deeper emotional connection with the consumer", as part of an ongoing three-year brand exercise by the company.
Sean Hastings, vice-president of product and marketing at Speedo International, said: "Everyone has a swim they remember, and it is these that make us really love swimming. This is an exciting new campaign, which will really drive consumers to get thinking about their most memorable swim."
