Finding your true threshold can feel like a mystery, but it’s one of the most important numbers in running. In this episode, I break down the most common ways to test it, from simple guesses to high-tech lab data, and uncover which methods actually help you run faster. You’ll learn why threshold matters so much, how it affects your training and racing, and what practical steps you can take to lock in your pace without wasting time or money. Key Takeaways Threshold training is the key to racing stronger because it tells you the fastest pace you can hold without crashing.
