The intensify block
Weeks 17 to 21 push the long sessions toward race-plus distances: runs of seven to eight miles and swims of 2600 to 3000 yards. Continuous high-intensity blocks lengthen again. A candidate who has stayed healthy through this block is in a strong position; a candidate carrying a nagging injury should back off the long days rather than the intervals, because the intervals are what move PST scores.
