Lactate Threshold (LT) is also referred to simply as threshold. Lactate Threshold Power is also referred to as functional threshold power (FTP).
Lactate Threshold Pace, Heart Rate, and Power all refer to the maximum effort you’re able to maintain with mostly aerobic energy systems
For most trained athletes this is similar to the maximum effort they can maintain for an hour.
Going above this threshold effort will result in a “burn” in the muscles and, after a few minutes, require stopping or slowing in order for the body to clear the lactate acid.
As endurance athletes, we want to go as fast as we can for as long as we can. Therefore staying under or right at the lactate threshold allows us to go hard, but not so hard that we have to stop.
