The Science of How Lactic Acid Really Works for Runners

Have you ever been running a race or workout, feeling strong, running faster than you ever have before, and you start to think about how great it is going to feel when you cross that finish line with your big PR?

But suddenly your body starts to shut down. You hit the wall, hard, and you can barely move your legs. Every step is like trying to bring your legs out of mud, and your legs go numb or even start tingling.

So, what happened?

Well, you have probably heard people throwing around the word lactic acid as the cause of all your end of race pain and struggle.

It’s been blamed for fatigue, soreness, overtraining, and probably more, but until recently, the phenomenon of lactate accumulation during intense exercise was poorly understood.

Today we will dispel some of the myths about lactate at threshold, how to avoid lactic acid buildup while running, and how you can prevent fatigue while improving your lactate clearance.
