Lactate threshold

• ↔Zone 2 training

  The lactate threshold splits training intensity in two. Below it you can pile up a lot of volume, which drives mitochondrial adaptation; the gray zone around it is thought to be a common reason amateur runners stall, because it is neither easy enough to do a lot of nor hard enough to raise the ceiling.

• ≠DOMS soreness

  Lactate is usually cleared and reused within an hour after exercise stops, while delayed-onset muscle soreness arrives a day or two later, so the timing does not match. Lactate is not a fatigue waste product either; it is a fuel that the heart, other muscles and the liver take up and use.
