Lactate and hydrogen ions are by-products of anaerobic metabolism and are released into the muscles when you start to exercise at a higher intensity. Hydrogen ions make the muscles more acidic and interfere with some of the enzymes responsible for making energy, which means that we start to fatigue pretty quickly in their presence.
Running at lactate threshold pace however, improves your body’s ability to buffer the lactate and therefore delays fatigue, which in essence enables you to run at a faster pace for longer.

So, the science is nice, but how do you know what your threshold pace is?
- : If you were to gauge your effort on a scale from one to 10 – where a steady run would be around a five and a race would be close to 10 – then threshold effort should rank at an eight.
How to do threshold running
Many exercise physiologists and coaches argue that lactate threshold isn’t an exact science so the best way to ensure that you hit the correct pace is by using a progression run.
