Intensify block, weeks 17 to 21

Week 19 of BUD/S Prep

Continuous sessions grow to two by 16 minutes. The long run is 7.5 miles. If a retest PST is due, do it early in the week, before the long run.

What changes from week 18

  • Monday, long slow distance run: 7.25 miles to 7.5 miles
  • Tuesday, continuous high-intensity swim: 2 x 14 min to 2 x 16 min
  • Thursday, long slow distance swim: 2700 yards to 2800 yards
  • Friday, continuous high-intensity run: 2 x 14 min to 2 x 16 min

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.
