As part of these daily musings I will attempt to demystify and explain in simple terms some of the things that confuse us or is just plain bad advice (IMHO). And today we start with the premise that to run fast you need to run FAST.
Well, there is some sense in that statement. If you want to run a 10k in 50 minutes you need to be able to run each kilometre at an average time of 5 minutes. Even I can do that math.
But the thing is you don’t have to train at that pace routinely. In fact training and running at that pace will actually be counter productive in a number of ways.
Before I explain, my premise is that most of my coaching clients are targeting longer endurance based races, not 100m track meets.
When you start your running journey most runners experience steep, exponential improvement curves and then things plateau. This is normal and shows the body is going through adaptation.
And this is where the problem starts. Once those physiological adaptations have taken place just doing the same thing again and again prevents any further improvement. This is often referred to as running in the Grey Zone i.e where no further adaptations occur.
So to run faster you need to run fast AND slow.
It’s the slow bit that sounds counterintuitive. And in fact easy paced runs should account for around 75-80% of your training runs. But why?
Running at around 65-75% of your maximum heart rate is where the body learns to be efficient in using your glycogen stores, in other words all those carbs we are encouraged to consume on our long slow runs. Run too fast for too long and the body ‘burns’ through the glycogen faster than you can top it up and store it. Fatigue sets it, form declines, etc, etc.
Now if you can reach that balance of carbs in = glycogen used then pace stays higher, form stays better and that pace will be maintained for longer and this is where you ‘get faster’ over any given distance. I
t’s the slow runs where the body is learning to work at this optimal level. It’s called working in the Aerobic Zone.
There is room for running fast too and this where speed work and intervals play their part. If you’ve never run at your required quicker pace then your body and brain can’t just pick it up and go with it without thinking your trying to kill them.
So speed based intervals over short, sharp distances teach the brain and train the physiology to run fast. It will help you improve cadence (the speed at which your legs turn over ) and generate more power too.
Just don’t do this in every session because you will burn out and increase your risk of injury.
So create a balance, look for training plans that hit those ratios of easy versus hard runs, and don’t worry that your running too slow. Because you won’t be. Good Luck.
