Marathon Training: Why Does Lactate Threshold Matter?

Hi, my name's Marcus Brown and I'm a World Marathon Major Six Star finisher and this will be my third Berlin Marathon (supported by Sportsshoes and adidas).

In the latest episode of my Berlin Marathon training series, I look to understand what pace I should plan to run the marathon.

I attend the University of East (UeL) London Human Performance Clinic to undertake a Pro Lactate Threshold test, which was conducted by Dr Andy Galbraith, Associate Professor in Exercise Physiology and Richard Avery BSc, MSc, CSci, AFHEA, Applied Sport & Exercise Scientist.

WHAT IS LACTATE THRESHOLD?

There are two lactate threshold levels, which your body produces when you exercise.

The first lactate threshold is the effort you can maintain for longer runs. There is a build-up of lactate, but it is at a level where you can process it, and you can maintain it for a long run i.e a marathon.

The harder you work, then the lactate will build up in your blood and cause the burning sensation in your muscles that will make you either reduce your effort or make you stop. This is known as the second lactate threshold. Where you get that burning feeling when your body ends up building too much lactate and our body can’t reprocess it to give ourselves more energy.

WHY DOES LACTATE THRESHOLD MATTER AND HOW CAN IT BE TESTED?

Knowing what your lactate threshold is, gives you a clear understanding of what effort you can sustain for the marathon. And I’d highly recommend it. 

If you want to get a test done at the UeL Human Performance Clinic the team will help you out, please let them know you found them from this video.

The test costs £80. To get in touch with the team email humanperformanceclinic@uel.ac.uk 

Prior to undertaking the test, based on my training and heart rate zones I calculated what I thought my target marathon pace was, and I ran to that pace/effort at the Big Half Marathon.

Post the Berlin marathon, I will follow up in a future episode to see if the finish time correlates with my lactate threshold test.
