Swimmer sets record by spanning 250 feet beneath ice cover, on a single breath, wearing only a Speedo.

Stig Severinsen says of remarkable feat, 'I just sleep almost, in that emptiness and that freedom. I kind of do everything in slow motion'.

Swimming a distance of 250 feet beneath the surface on a single breath is no simple feat. But throw in the fact that the swim is under three feet of ice cover, and the swimmer has no wetsuit–only a Speedo–and the feat becomes downright remarkable.

So remarkable that Stig Severinsen’s recent 1-minute, 26-second jaunt beneath an ice-covered lake in East Greenland, to an escape hole 250 feet away, has been recognized as a Guinness World Record.
