Greatest distance swimming underwater in 1-hour

Today, I am attempting to set a Guinness World Record by swimming 100 x 25m laps underwater in 1 hour using DNF (Dynamic-No-Fins, aka underwater breast stroke) technique . Watch live as I try to overcome physical and mental barriers and do something no woman has every done before!
