The most accurate way to find your lactate threshold costs $250 in a lab, but the second-best method is completely free and you can do it this afternoon!
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.
- With the right approach, you don’t need fancy labs or expensive gear—you can get reliable numbers from simple tests and consistent training.
- For most runners, a simple 20-minute field test is the most effective way to find your threshold heart rate. It is surprisingly accurate, empowering, and something you can repeat every month or two to track your progress without needing a lab.
