S10 day 1 – clean, hip/ab ok, but general fatigue (calves/foot/hips) plus a scheduling conflict prompted shortening this whole week rather than pushing into the build volume it was supposed to step up to.

The coach’s read

6.50 km in 43:26, HR 128/149, 55 % Z1 / 43 % Z2 / 1 % Z3 – clean discipline, low HR. Hip and ab held up fine today, but general tiredness from Sunday’s long run plus a broader pattern – 7-day RHR ticked to 42 (the green ceiling), HRV dipped, and calves/foot/hips all reporting some fatigue at once, not one specific flare – landed right as the plan was stepping back up from last week’s deload into a 23 km build week. Combined with an unrelated scheduling conflict (weekend renovations forcing Saturday’s long run to be skipped anyway), the call was to lean into it: skip the long run with no makeup, trim Wednesday’s medium-long to easy pace, keep Thursday light. Documented in course.org as an unplanned mini-deload – proactive, not injury-forced, and cheap against a 30 km goal that’s still ~7 weeks out.

Part of week 10 of the 30 km build.
