Our Keynote Speaker for March 8, 2024

Sarah Thomas

Champion Swimmer & Inspiration to us all!




Sarah Thomas, 41, 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 (NY/VT) in August of 2017. Shortly after completing this swim, Sarah was diagnosed with an aggressive form of breast cancer. She was just 35 years old. While undergoing aggressive cancer treatment, including chemotherapy, surgery, and radiation therapy, Sarah never gave up on her dream of doing a swim that most people thought was impossible. One year after completing her cancer treatments, Sarah did just that- becoming the first person in history to complete a four-way crossing of the English Channel in 54 hours and 10 minutes. Recently, Sarah became the first person in history to complete a two-way crossing of the North Channel, from Scotland to Ireland and back to Scotland in 21 hours and 46 minutes in freezing water, peppered with giant jellyfish.

Sarah lives in Conifer, Colorado, with her husband Ryan, their two beagles and their rescue mutt. She is a full-time veterinarian recruiter. She also does keynote presentations for special events, where she shares life lessons that have helped her complete marathon swims and beat cancer.
