However, there are different definitions of where that occurs. The chart above has my lactate threshold heart rate at 168. That's way too high and while I am a running savant so expected solid results, that's too high.
Fast lab obviously defined my lactatate threshold heart rate at 4 mmol/L. That's mostly outdated, now people are using Dmax, 1 mmol/L above baseline, max steady state lactate threshold, etc etc.
It gets complicated with all these different definitions. But the important part is find your aerobic zone. And luckily, there is zero debate there. On my graph, my baseline blood lactate is 1.3 mmol/L. And as you can see, up close to 8 minute miles my blood lactate remains unchanged. I am using all fat to run, it's when I start using carbs that my blood lactate starts increasing.
There has been tons of research on endurance training, from running to rowing to cycling to swimming. All the research shows that training 80% of the time aerobically is optimal for improvement, in both amateurs and professionals.
Yet what do running donks train like? They all love to train too much in the higher intensity zones. Donks train up to 50% at higher intensities, mostly at where the body starts building up lactate. These people get injured, find running is not sustainable, and in general just hate it. But it's mostly because they train like donks.
Running should be enjoyable and that is done by mostly running at your aerobic heart rate. That's why it's so important to know your lactate threshold, to basically avoid working out too much at that particular zone and higher.
Luckily, lactate threshold correlates almost close to 100% to race performance. So you can find all your zones by taking a balls out race and inputting to Jack Daniels or McMillan calculator. No need for fancylad bloodwork.
So yeah I burned $150 in testing. But it proved that I am doing things correctly. Also, some research has been done and marathon pace is pretty much at 1 mmol/L higher blood lactate than baseline for most. So for me that would be 8.1 mph. I ran Berlin at 8.3 mph, but I am worse shape now. So for me that is absolutely right. To reach my goals I need to shift my lactate threshold to the right, so that at 8.5 mph I am at 1 mmol/L higher than baseline. So I need to get my easy miles down into the mid7s in minutes. And I mainly do that by running 80-85% of my miles aerobically at my current easy pace of 8:10. I am getting old so I will probably do 85 percent aerobic / 15% high intensity.
This is a change from last year, where I was training more like a donk because I used outdated running programs based on higher intensity. I am drinking the lower intensity kool-aid this year by mainly adding what I considered junk mileage last year, recovery miles. Hopefully it works, it sure is much more enjoyable. Fack tempo runs.
