This is one of the biggest questions we get from those new to the training. They need reminding that the first development is endurance and has nothing to do with final race time. The goal in Phase One is to get used to “time on your feet” for building mitochondria on your slow twitch muscle fibers, and to stimulate other circulatory and muscular-skeletal infrastructures. As you progress up the pyramid increasingly simulate race pace. Many people find that by switching to Lydiard training that their race pace is actually much quicker than they thought they were capable of and make a quantum leap in performance.
