Run
Lidingö taper — volume down, keep intensity touches. From 12 October, three runs a week unbroken, 30 to 60 minutes, one extending toward 90.

Training volume in heart rate zone
Complete weeks only.
Training volume by pace zone
Grade-adjusted pace, what you produced; heart rate above is what it cost.
Running economy
Vertical ratio in a fixed pace band. Lower is less wasted bounce.
Cadence and ground contact
At the same pace band. Falling cadence usually means fatigue, not choice.
Average pace by heart-rate zone
Weekly grade-adjusted pace held within each heart-rate zone, first ten minutes of every run excluded. Each zone splits into a lower and upper half — the full span is too wide for one average to show improvement.
Fade
Grade-adjusted pace at fixed heart rate in the final 30 minutes against the first 30. The marathon-relevant durability number.
Training paces
Derived from your best recent race using Jack Daniels' VDOT tables. These are prescriptions, not measurements — what to run, given what you have raced.
Distance profile
Left–right balance
Watched as running volume climbs, given the hip history and the calf/Achilles asymmetry. Compared against your own baseline, not a textbook 50/50.
