In the endurance world, the term Lactate Threshold is commonly used to refer to the heavy-severe intensity domain boundary. It is sometimes used interchangeably with the (now obsolete) anaerobic threshold. We use intensity domains to describe distinct physiological responses to exercise.
Estimated lactate threshold pace = 7,258.141 meters/1,802 seconds = 4.03 meters per second. But meters per second is kind of useless for us metric avoiding residents of the United states of America. So how do we convert that to miles per hour? Multiply the rate of meters per second by 2.2369 So, 4.03 m/s x 2.2369 = 9.01 miles per hour.
Lactate-threshold pace is about 10 to 15 seconds per mile slower than 5K race pace (or about 10K race pace) for slower runners (slower than about 40 minutes for 10K). If using a heart-rate (HR) monitor, the pace is about 75 to 80 percent max HR.Workouts to improve lactate threshold pace. Pace/tempo training uses an intensity at or slightly higher than race competition intensity. This intensity corresponds to the lactate threshold; therefore, this type of training is often called threshold training. There are two ways to conduct pace/tempo training: steady and intermittent.
What Is Your Threshold Pace? Threshold pace—also known as T-pace—can get a little complicated. In scientific terms, this is the pace at which your body needs to produce energy without oxygen. It does this using glycolysis, which produces a byproduct called lactate. A person's lactate threshold is when the production of lactate exceeds their body's ability to clear it from the system. Research suggests training around one's lactate threshold could beLactate threshold, also known as anaerobic threshold due to the absence of oxygen, is the intensity of exercise at which lactate begins to accumulate in the blood at a faster rate than it can be removed. Any runner, whether a beginner runner or a seasoned runner, knows the feeling: you're running along, and then suddenly, your legs feel heavy.
Put simply, the lactate threshold is an exercise intensity where blood lactate shows an accelerated increase. The image below highlights the relationship between exercise intensity and lactate levels. At low intensities, lactate remains low, until a point referred to as the aerobic threshold (LT1).
Lactate Threshold is the pace or effort that you can sustain for a prolonged period of time where the amount of lactate that your muscles are producing can effectively be removed. For most runners this is the fastest pace you can maintain for 1 hour. For Elite Runners this pace is similar to 15km to Half Marathon race pace.
Lactate threshold is the point where lactic acid begins to accumulate in your muscles - your body switches from aerobic respiration where lactic acid is easily moved out of the muscles, to anaerobic respiration where lactate builds up.
Lactate threshold is pinpointed where the blood lactate concentration begins to increase rapidly. In a typical trained athlete, that point corresponds to roughly 85 percent of maximum heart rate
According to the science, to estimate your lactate threshold, divide the distance covered in metres during that time by 1,800 seconds (30 minutes). For example, a runner covering 8,000 metres in 30 minutes has an estimated lactate threshold of 8,000 metres divided by 1,800 seconds = 4.5 meters per second.
So, what is Threshold training? This is running at a pace where lactate does not rise significantly in the blood during the run, but rather, it stays at a constant level. Essentially, it is the point JUST BEFORE the moment where the amount of lactic acid build-up is greater than the body can efficiently get rid of.
