Threshold running explained
Threshold running helps you run faster, for longer.
In scientific terms, threshold running increases your lactic threshold, which is the point at which your body fatigues at a certain pace.
The main benefit of threshold running is that your muscles get used to running at this effort level. As you continue your training, you'll find yourself able to sustain this type of fast running for longer.
The most important thing is to run at an effort level between 8 – 8.5 out of 10 (1 being rest and 10 being flat-out effort). This level of exertion allows you to stress your body to a manageable level, but also lets you recover, adapt and improve.
You can do 1 or 2 threshold running sessions per week. You might not get it right first time. But keep trying. After a few weeks you'll notice a huge difference. Your fast runs will be quicker and your slow, steady runs will feel like a breeze.
