Lactate Threshold

Lactate threshold is the exercise intensity at which lactate (lactic acid) starts to accumulate in the bloodstream.
In running, it is the estimated level of effort or pace. When a runner exceeds the threshold, fatigue starts to
increase at an accelerating rate. For experienced runners, the threshold occurs at approximately 90% of their
maximum heart rate and between 10k and half-marathon race pace. For average runners, the lactate threshold
often occurs well below 90% of maximum heart rate. Knowing your lactate threshold can help you determine
how hard to train or when to push yourself during a race.
If you already know your lactate threshold heart rate value, you can enter it in your user profile settings
Your Heart Rate Zones, page
