In this episode of the UKRunChat podcast, Michelle is joined by USA Triathlon coach and author Hilary Topper to talk about her new book, Unlocking the Triathlon: A Beginner's Guide to Competing in a Triathlon. Hilary shares her journey from failing gym class and not knowing how to swim, to taking up triathlon in her 50s, and even an 8.3-mile open water swim. She explains why triathlon is truly accessible for everyone, how runners can make the leap into multi-sport, and why cross-training can make you a stronger, more resilient runner. We cover: * Hilary's journey from treadmill newbie to triathlete and coach * Why she wrote Unlocking the Triathlon * Practical tips for beginners: training plans, essential gear, and transitions * How swimming and cycling can improve your running * Balancing training with work, family, and life * Why triathlon isn't just about racing If you've ever thought "Could I really do a triathlon?" this episode might just convince you the answer is yes. Unlocking the Triathlon: A Beginner's Guide to Competing in a Triathlon is out in January 2026 and is available for pre-order on Waterstones and Amazon.
