Lifting the lid on lactate
Lactate threshold: you probably have an idea of what it is. Or maybe not
01/ AEROBIC THRESHOLD (aka LT1 or, confusingly, lactate threshold). The point where blood lactate begins to climb above the baseline. Around 2mmol/l blood lactate, an intensity at which you can run for two hours or more.
02/ LACTATE THRESHOLD (aka LT2, lactate turnpoint, anaerobic threshold). A sharp increase in the rate of lactate accumulation. Around 4mmol/l of blood lactate; a pace you can maintain for 45-60 minutes.
