| 1 | Raise background volume 32–35 → 38–40 mi | The 2027 marathon build requires a 38–42 mi background to start from, and Oct 4 measured the cost of not having it: HM-equivalent VDOT 44.8 against 46 at 5K. One point of drop-off at 13.1 off a 42 mi peak week. The gap widens with distance, so at the marathon it will be larger than one point until this number moves. Volume is the stimulus of this block; everything else is maintenance. |
| 2 | Hold threshold fitness 1 T session/wk, 2 from Wk 6 | Off-block periods are load-bearing — they set the floor the next build starts from. Full intensity withdrawal would hand back the T work that took Jul–Sep to build. This is a hold, not a progression: no I work, no HMP work, nothing to peak for. |
| 3 | Run the calf ramp 20 → 50 lb | The most overdue item in the program. It has sat between bodyweight and 20 lb for the entire half build because every taper stripped it. Target is 0.25–0.35× BW (45–55 lb at 155) for sets of 10. There is no race to protect for 12 weeks — this is the only window it gets. |
