Today’s guest is a phenomenal swimmer, who relishes the cold: she has completed the British Triple Crown, the English Channel, Bristol Channel and the gnarly North Channel: which she swam after being blown out for a year, only to break a record and become the earliest female, swimming that stretch of water in just under 19 hours in 12 degrees of water. An incredible swim. She has swam three ice miles, and also completed the chilly Loch Ness in 18 hours… it’s Dr Jo Stokoe!
