Unlocking the Triathlon: A Beginner's Guide to Competing in a Triathlon with Hilary Topper

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.
