Cath is a Guinness World Record Holder for the most Southerly Ice Swim (Female), she achieved this record by becoming the first person in the world to swim an ice mile inside the Antarctic Polar circle in February 2020. Her story was captured by the BBC for a documentary about ordinary people achieving extraordinary things, titled “The Merthyr Mermaid” and is available to watch on BBC iPlayer – The Merthyr Mermaid. Cath has always used exercise as a way of helping her to manage her mental health. She discovered her passion for winter/ice swimming in September 2015 and was immediately hooked, since then Cath swims as much as possible and she refers to it as her “Reset Button” and says “to make Cath happy, just add cold water!”
