A 100-mile world record time sounds like something from another planet, until you hear how Caitríona Jennings actually built it: not with superhero secrets, but with structured habits, a trained mindset, and the same calm problem-solving you’d expect from a top Chartered Accountant. Caitríona is an Irish Olympian who moved from triathlon into marathon running, qualified for the 2012 Olympics while working full-time in PwC, and later pushed into ultrarunning to set a stunning 100-mile record of 12:37:04. 

We dig into the real work behind endurance performance: time management while studying and training, removing friction through weekend planning, and staying injury-aware. Caitríona opens up about the Olympic marathon that went wrong, why finishing still mattered, and how that experience shaped her resilience. We also explore practical sports psychology tools like positive self-talk, intercepting negative thoughts, and visualisation so your brain treats pressure as familiar. 

Then we switch lanes into career growth and aviation finance. Caitríona explains how she pivoted from tax into a commercial role on an aviation leasing trading desk, buying and selling aircraft that are on lease to airlines. It’s a clear example of how the Chartered Accountancy skillset travels: analysing financial statements, understanding risk, communicating with customers, and making calculated moves without being reckless. If you care about leadership, performance under pressure, and building a career with range, you’ll take notes.
