Sub-50 10K · 16 weeks from 2026-08-10 · week 9
The plan
One workout per slot per week, one hard session at most — and from week 4 that session is Sunday's football. Base → threshold → 10K-specific → peak → goal window, with down weeks at 4, 8 and 12.

Pure easy — the default, and the one to pick when in doubt35m · 5.3 km
Easy + strides — keeps the legs quick without costing anything aerobically36m · 5.6 km
Short shuffle · 30 min — the version that still counts on a bad day30m · 4.4 km
Walk / run · 35 min — for the day after football, or the day something is grumbling28m · 4.1 km
The rules
- Easy means easy: 6:20-6:50/km, conversational, HR under 150, every single time. These runs exist to add aerobic time — the moment they turn into moderate running they start eating Thursday's session instead of feeding it.
- Time, not distance. Thirty minutes is thirty minutes whether it is 4.4 km or 5.0. Run the route out-and-back and turn at half time; chasing a distance at lunch is how an easy run becomes a tempo.
- Never the day before the long run, and never the day after football. Wednesday is the day; Tuesday's easy slot is the other lunchtime run, and Friday is not a lunch-run day in this block.
- One a week, and never more in this block. Weekly volume is capped at roughly 1.3× the biggest week on record (25.6 km); the half-marathon build in the new year is where more belongs.
- They are the first thing to drop when tired, sore, or with a niggle open — but they are not optional in the sense the evening recovery jog is. From November they are the week's daylight running.
- Flat and familiar. Lunchtime is not the moment to explore, and descents are what the knee objects to.

Sunday
Terrain, per session
The rules of the block
- Choose exactly one workout from each required slot per week.
- Choose at most one quality workout per week.
- Optional recovery run is only added when recovering well.
- Keep at least one easy or rest day between quality and long sessions when possible.
- If unusually fatigued or sore, choose the easiest option or rest.
- Sunday football IS that week's quality session: 60 minutes on a quarter pitch as a winger, 20-30 near-length efforts — that is a repeated-sprint workout by any other name. Never run 400s, strides or a time trial in the same week; if you want a second quality run, make it the tempo or threshold option, which is the one thing football does not train.
- Swimming counts as the optional recovery session: easy, unmeasured, no impact. It never replaces a required running slot — aerobic fitness in the water does not transfer to running legs.
- Every week is Tue easy (at lunch on the flat route when the day allows) · Wed lunch run, plus an optional evening swim · Thu quality · Sat long in the morning · Sun evening football. Monday and Friday are off. Nothing runs on Sunday: the day is the game.
- Run Saturday's long run in the MORNING. Football is Sunday evening, so an early Saturday leaves ~36 hours before 20-30 near-max efforts instead of ~30 — sprinting is where hamstrings go, and the recovery window is the cheapest protection available.
- Lunch run (Wednesday) is volume, not a session: 30-35 minutes at 6:20-6:50, HR under 150, always easy, one a week, never the day before the long run. Tuesday's easy slot is best run at lunch too — the same flat route, the same cap. From November these two are the only daylight running in the week.
