Sarah Jarvis

Born and raised in a sporty family in Germany, Sarah Jarvis got into triathlon at the age of 16 and immediately fell in love with the sport. She successfully worked her way through the German junior ranks in the short distances and became certified as a youth triathlon mentor while in high school in order to share her passion with others. In her early twenties, she moved to the US where she established herself as the top Utah age grouper for many years. As a wife and mother of two boys, Sarah placed on the podium in several 70.3 World Championships and decided to take her pro card in 2014 to challenge herself further and experience the sport at the highest level. After two successful decades in triathlon, she is currently facing a significant change with her recent diagnosis of a severe auto immune disease called rheumatoid arthritis. However, her passion for and dedication to triathlon is stronger than ever and Sarah has really enjoyed bringing people into the sport and mentoring them for years before officially starting as a coach with Multisport Mastery in 2016. Sharing her extensive knowledge and love for this sport with others is what brings her true joy.
