Breaking the 100-Mile World Record: Caitriona Jennings on Ultra-Endurance Success

ISESA Podcast

Show Notes

Most of us would struggle to drive a car for 12.5 hours without losing concentration. Caitriona Jennings ran for that long—averaging a blistering 7:34/mile pace to shatter the 100-mile World Record. In this episode, Bruce sits down with the 2012 Olympian and new ISESA board member to discuss one of the most remarkable feats in Irish endurance history. We explore how she balances her C Suite role (Vice President in Aircraft Trading) with elite ultra-running, often flying straight from a race finish line back to the office. We also revisit the heartbreak of London 2012, discussing how finishing last on a stress fracture became the foundation for the mental steel required to excel in the ultra-running world.

Key Topics Discussed:

The World Record: Breaking down the 12:37:04 run at Tunnel Hill—pacing strategy, fueling with high-carb gels, and the mental battle of the "figure of eight" course The "Dual Career": How Caitriona manages 100-mile training weeks while holding down a high-pressure corporate role in aviation leasing Resilience: Why the trauma of London 2012 ultimately prolonged her career and prepared her for the pain cave of ultra-running Training Philosophy: How a mature athlete manages volume, avoids injury, and uses the weekend for "compounding" long runs What's Next: The hunt for the "Green Number" at the Comrades Marathon 2026.

Image and performance enhancing drug use is changing rapidly and it is no longer confined to elite sport or competitive bodybuilding. In today's, Bruce speaks with Dr David Nolan about his new research examining iPED use in Ireland. They discuss what people are taking, why they are taking it, the growing prominence of peptides, the influence of GLP-1 drugs and testosterone replacement therapy, and the increasingly blurred line between treatment, enhancement and aesthetics. The conversation also explores health monitoring, the limits of blood testing, barriers to engaging with healthcare professionals, the challenges of coming off iPEDs, and why this is not exclusively a male issue. David’s study provides an important first snapshot of a poorly characterised area of health and performance in Ireland, with plans to repeat the research over time and build a clearer picture of how the landscape is evolving.
