What changes from week 15

  • Monday, long slow distance run: 6.5 miles to 6.75 miles
  • Tuesday, continuous high-intensity swim: 2 x 12 min to 2 x 14 min
  • Thursday, long slow distance swim: 2400 yards to 2500 yards
  • Friday, continuous high-intensity run: 2 x 12 min to 2 x 14 min

The load block

Weeks 12 to 16 are the middle of the program. Interval days reach their ceiling of ten reps and stay there, so the progression shifts to the long days and to the continuous high-intensity sessions, which split into two blocks with a rest between them. Core work adds a third set. This is a good block for a retest PST, because the calibrated paces from week 1 are probably too slow by now.
