The lactate threshold (LT) (or lactate inflection point (LIP) or anaerobic threshold (AT)) is the exercise intensity at which lactate (more specifically, lactic acid) starts to accumulate in the blood stream.
For athlete 1, this is confirmation that their anaerobic threshold pace is reasonably accurate. For Athlete 2, lactate begins to accumulate during the middle 15minute segment (their estimated threshold) and continues to do so during the final 15 minutes.
