Block heart rate 157.3 / 159.2 / 161.2 / 162.1, whole-run max only 173\. 31.5 km total. Run at 3-hour marathon rhythm while pacing another runner, so the work pace was a commitment rather than a free choice. | | | | | | | ### good - Sunday's 4 x 6 km off 1 km floats ran 4:15.5 / 4:10.7 / 4:09.5 / 4:09.7 per km at heart rate 157 / 159 / 161 / 162, whole-run max only 173\. Twenty-four kilometres of work getting faster while costing almost nothing cardiovascularly. That is the strongest aerobic datum in the file since the marathon. - Tuesday's 400s came in at 84 to 87 seconds once the opening set was through — 3:27 to 3:30 per km — off 45-second floats, heart rate 168 to 173 and holding steady rep to rep rather than climbing away. - Thursday evening carried the most 10 km-specific session of the block: 2 x (4 min + 8 min) at 3:38 to 3:42 per km off short floats, heart rate 170 rising to 178.4 on the final 8-minute block, max 185\. Bracketed by eight 30-second strides at roughly 3:15 to 3:20 per km. - Friday's 2 x 20 min ran 4:11 then 4:00.6 per km over 197 m of Cottesloe elevation. Second block faster than the first on tired legs. ### note - Two race commitments now shape the training at once: a 3-hour marathon pacing job in Perth on 11 October, and the 10 km relay leg on 8 November. The long runs at 4:09 to 4:16 per km are pacing-specific; the midweek work at 3:27 to 3:42 is 10 km-specific. Both streams are present and neither is diluting the other so far. - 101.5 km is the highest week since the marathon build and the third week after a marathon. The progression reads 43.7, 84.5, 101.5\. Symptom-free throughout. - Sunday's pace was partly set by pacing someone else to 3-hour rhythm, so the work-block paces are a commitment rather than a free choice of effort. - Four quality days inside six, with a 24.4 km easy run at 4:52/km on the Wednesday as the only true recovery running in the week. - Strength continued, 36 minutes on the Monday with no run that day. No exercise detail is recorded in the source. ### watch - Nothing continuous beyond 8 minutes at 10 km pace. The longest unbroken block at or under 3:42/km all week was 2.16 km. Volume at goal pace is abundant; continuity at goal pace still is not. - The 4 x 6 km at 4:10 costing only 161 heart rate and the 400s at 3:27 costing 170 sit oddly together — an aerobic base well ahead of what the top-end speed currently converts into. - This week was reconstructed seven days late. Session detail is complete from the stored files, but no contemporaneous notes exist.
