Meet Your Coaches:

Sarah Thomas

Sarah has been a competitive swimmer most of her life, competing through high school and for the University of Connecticut. After moving to Denver in 2004, she found a masters team who convinced her to try open water swimming. The rest is history.

Sarah lives outside of Denver, at least a 30-minute drive from all bodies of water. She loves her husband, Ryan, and their three dogs. For her day job, she is a veterinarian recruiter.

Sarah specializes in working with adult swimmers who have completed swims beyond a 10k and are looking to take their open water swims to the next level.
