South African free diver Amber Fillary, 46, will try to break a world record on Thursday in an icy lake in Finland after struggling with an eating disorder, alcoholism and bouts of suicidal depression.
"I am under no illusion that this is not going to be easy. In South Africa I managed to swim underwater for up to 135m without taking a breath, but in near-freezing temperatures your muscles are slower, so swimming is much more challenging as you use more oxygen"” Fillary, whose record for holding her breath under water is six minutes, said on Wednesday.
Johanna Nordblat is the current record holder who dove 50m under the ice in 2°C temperature water in March 2015 wearing only a swimsuit, mask and cap.
Nordblat challenged Fillary two years ago while Fillary was getting her world record attempt into place, but Fillary declined as she was struggling from depression.
