Getty Threshold work is one of the cornerstones of training for runners who are tackling distances from 800m to ultras. Your lactate threshold is the point at which lactate is produced and Lactate 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. Your lactate threshold is the level at which the intensity of exercise causes lactate to accumulate in the blood at a faster rate than it can be removed, making it the border between low- and Lactate threshold 2 (LT2) - point of accelerated increase While, races are less accurate for establishing the heart rate at lactate threshold, you can use races to establish the pace or power at the lactate threshold. With time trials, research has found the 30-minute time trial method to be a good predictor of velocity and HR at the LT 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. Tempo pace is different for everyone, which is part of the appeal of this training technique. It's customized to your current running capabilities, and it changes when you do. Much like aerobic exercise is a workout for your heart, training at your lactate threshold is a workout for your muscles to practice clearing lactic acid buildup. KD2u.
