Claire first fell in love with running as a member of her high school’s cross-country running team. As someone who mostly focused on academics and music, she never considered herself much of an athlete but found joy in movement and competition. After a long break from running, Claire discovered distance running in her 20s while living in London, and the sport literally changed her life. Training for her first marathon connected her to her husband, and competing in subsequent endurance events inspired her leave the corporate world to pursue a career as a Sports Dietitian. 


Over the last 25+ years, Claire has competed in numerous solo and team events from the 5km to 50-mile distance. She particularly enjoys trail running and has completed a number of trail ultras and marathons, including The North Face DC 50k, UTHC 65kJFK 50, Sean O'Brien Trail marathonRodeo Valley 50k, Mt. Tam 50k, and Canyons 50k. Claire also has competed in numerous road marathons, including the Boston Marathon in 2013 and 2014.  

Claire spent 15 years in NYC and now lives in her hometown of Aptos, CA with her husband and two young girls. She loves to run in the redwoods and on the beach, hunt for sea glass, and garden. Stay current with her adventures on social media (@eatforendurance) and through her Podcast.
