Pat’s instructions called for me to hit 40 seconds per 200 during the hard intervals in the first set, take four minutes rest, then resume and aim for 38-40 seconds on the hard intervals. The first set I was dead on the pace, knocking out between 39-41 seconds per lap on every hard 200. After the break I came back and hit 36 seconds and change on the first interval. Blazing. A little too blazing. That extra two seconds per 200 had me breathing much heavier and feeling “that feeling” in my obliques.
