52 year old Colin Pringle, from Wallington, South London, died in hospital after participating in the Great North Swim in Windermere, Cumbria, on Friday.
The Great Swim Series is the UK's biggest exhibition of open water swimming and is staged in clean and safe lakes, lochs and docklands in various areas of the country, according to its website.
The Great North Swim features half-mile, one-mile, two-mile or 3.1-mile courses, with "expert safety kayakers" accompanying swimmers.
