When life gets hard, many of us channel our inner Dory, put our heads down, and “Just keep swimming.” Nobody, but nobody, embodies this ethos more than this week’s guest ultraendurance swimmer Sarah Thomas. In Sarah’s 40 years on this planet, she has endured chemo, radiation, and surgery for aggressive breast cancer, a traumatic ectopic pregnancy, and the challenges of cancer-related medical menopause. She has also smashed preconceived notions of what is possible, becoming the first person to complete a four-way crossing of the English Channel in 54 hours and 10 minutes just one year after completing her cancer treatments. We talk all about her journey through the difficult, murky waters of medical menopause and her ability to literally swim for days despite the challenges and adversity she’s faced in her life.

Sarah Thomas is an ultra-marathon swimmer who holds the current world record for the longest continuous (unassisted, non-wetsuit) swim done in current-neutral conditions. That record-breaking swim covered 104.6 miles over 67 hours and was completed in Lake Champlain (USA) in August of 2017. Shortly after completing this swim, Sarah, then 35, was diagnosed with an aggressive form of breast cancer that demanded equally aggressive treatments. Through it all, Sarah never gave up on her dream of doing a swim that most people thought was impossible, a four-way crossing of the English Channel, which she completed one year after finishing cancer treatments. Recently, Sarah became the first person in history to complete a two-way crossing of the North Channel, 21 hours and 46 minutes in freezing water, peppered with giant jellyfish.
