Week 4
28 Sep – 4 Oct
How the week was run
Every session scored against what the plan asked for, weighted by its distance
- 36.5 of 37 km, 6 of 4 runs, longest 14.1 of 14 km.
- Execution 97% across 4 sessions, 4 of them at 90% or better.
- Most of what was dropped went on easy running done too fast. Easy days are where the week is banked — spending them costs the long run, not the easy run.
- Strength 1 of 1. Done, which is the non-negotiable part.
- Nothing to fix. Repeat this week as many times as the block asks for it.
The repeat week landed. Gym on Monday, all three midweek runs, and the 14 km long run on Saturday: 37.5 km against 37, every session on the board, the first complete week since week 2. The long run is the headline, and it was done well apart from one thing. 14.07 km, heart rate 132 on average, under 140 for the first twelve kilometres and only 143–145 in the last two; you stopped at 14 and did not chase 15, which was the right call. The one thing is pace. Strava's 7:51/km average includes about 16 minutes of walking and stopping. The running itself, 12.8 km of it, went at 7:37, eighteen seconds quicker than the 7:55–8:25 band and the same drift as last week's 7:34. The walk breaks made the average look right while the running stayed too quick. The easy days are still quick: Tuesday 7:58, Wednesday 7:54, Thursday 7:45, all against 8:10–8:45. Heart rate averaged 130 to 139 and stayed legal, so this is not week 1 again, but Thursday's 7:45 at 139 bpm is at the edge of it. Form, from Apple Health: cadence read 152 overall, but that average includes the stops; while you were running it held about 160, the same as your easy days. The number worth watching is ground contact. It averaged 273 ms for the first 25 minutes, close to Thursday's 264, then stepped up to about 303 for the rest of the run and never came back down. Same pace, same cadence, and the foot staying on the ground longer is what tired legs look like. It is the Osaka story at 14 km instead of 30, and it is what the Monday gym is for. Next: week 5 progresses as planned, 40.5 km with the first steady session and a 16 km long run, about 8% up and inside the 10% rule. Hold Tuesday and Thursday down at 8:10 or slower, so the steady blocks on Wednesday are the only quick running of the week.

Show Gym: legs
Gym — legs
7 exercises · 55 minMonday, on its own, with no run before or after it. At Osaka your heart rate averaged 144 against a zone 2 ceiling of 146, and you still lost 32 minutes in the second half. The engine was never the problem. The legs stopped absorbing landings, and no amount of extra running fixes that. This is the session that does.
- 1
Leg press
3 × 82 min restFeet hip width in the middle of the platform. Lower until your knees reach about 90°, keeping your lower back pressed into the pad — if it peels off, you have gone too deep. Three seconds down, push up through the whole foot, and stop just short of locking the knees.
Quads and glutes under real load — the muscles that absorb every landing, and the ones that gave out after 30 km twice.
- 2
Seated leg curl
3 × 1090s restSit back against the pad and bring the lap pad down snug on top of your thighs. Set the roller just above your heels, behind the lower leg. Pull your heels down and back under the seat as far as they go, pause for one second, then let them back up over three seconds. Keep your back on the pad — if your hips slide forward, the weight is too heavy.
Hamstrings, which pull the leg through every stride and are what cramps when the quads hand over the work late in a race.
- 3
Seated leg extension
3 × 1090s restSit back with your knees in line with the machine's pivot and the pad on the front of your ankles, just above the feet. Straighten both legs until they are level with the seat and squeeze for one second, then lower over three seconds. Hold the handles and keep your hips down — no swinging, and if you need momentum, drop the weight.
The front of the thigh, and the tendon below the kneecap that takes a pounding on every downhill — Kyoto has them.
- 4
Hip abduction
3 × 1560s restPads on the outside of the knees. Sit tall, push the knees apart as far as they go, hold for one second, and let them come back over two. Do not let the weight stack slam between reps.
The side of the hip — the muscle that stops your pelvis dropping on each stride, which by 30 km is what turns into the shuffle.
- 5
Hip adduction
3 × 1560s restPads on the inside of the knees, starting at a stretch that feels comfortable, not extreme. Squeeze the knees together, hold for one second, open back out over two. Sit tall throughout.
The inner thigh, which balances the abductors and keeps the knee tracking straight when you are tired.
- 6
Calf raise on the leg press
3 × 1260s restSame machine as the leg press, with a lighter weight. Put the balls of your feet on the lower edge of the platform, knees almost straight and never locked. Press up over one second, hold at the top, then lower over three until you feel the stretch below the calf. Your knees do not move — only your ankles.
Calves and achilles — your push-off, and the first thing to cramp at 35 km.
- 7
Plank
3 × 45 seconds45s restElbows directly under your shoulders, hips level with your shoulders, ribs pulled down, glutes squeezed. The moment your hips sag or your lower back arches, the set is over.
A trunk that does not collapse late in a race, which is when your form goes.
- Warm up for 5–10 minutes on a bike or a brisk incline walk. Not a run — the whole point of Monday is that there is no run.
- Weeks 3 and 4: learn the machines. Use a weight you could lift 15 times and do the listed reps. Soreness from new movements is real, and Tuesday is still a run.
- From week 5: pick a weight where the last rep of each set is hard but clean, with about two more left in you. When all three sets feel that way, go up one step on the stack next week.
- Three seconds on the way down, every rep. The lowering is where the strength comes from.
- If your legs are still sore on Wednesday, you went too heavy for Wednesday's session. Drop a step, not the day.
- Tuesday's easy run will feel heavy the day after. That is expected, and why Tuesday is easy.

What a stride actually is
A stride is 20 seconds of fast, relaxed running — and it is not a sprint. You wind up smoothly over about five seconds, hold something near your 5 km race speed for ten, then ease off over the last five. It is over before it gets hard, and it costs you almost nothing: after six of them your breathing should be normal within a minute. The point is not fitness. It is to remind your legs how to turn over quickly, because that is the first thing that disappears when every run is slow — and every run of yours is slow by design.
- Wind up over the first 5 seconds. Never explode from a standing start.
- "Tall" means running as if a string is pulling up through the top of your head: hips forward, chest open, no folding at the waist and no leaning back.
- "Smooth" means quick light feet landing under your hips, not long reaching steps out in front. You are chasing a faster cadence, not a longer stride.
- Shoulders, hands and jaw stay loose. If your face is straining, you are sprinting — back off.
- Ease down over the last 5 seconds rather than slamming to a stop.
- Then walk. A "full walk back" means actually walking, about a minute, until your breathing is completely normal again.
- If one stride feels harder than the one before it, the walk back was too short. These should never leave you out of breath.
- Do them on flat ground with no traffic, and never on a day your legs feel beaten up.

Long run 14 km
14 km planned· ≈ 1:51–1:58100%1080v1514 km easy, at the long-run band: 7:55–8:25, not quicker. Take a gel at 45 minutes even though you do not need it yet. Last week's 14 km was lost to rain, so this is the one that counts. You may stretch it to 15 km, but only if Tuesday to Thursday all got run (or a rained-out day moved to Friday), the shin is quiet, you feel normal on Friday, and the first 14 km stayed in the band with heart rate under 140. If you have drifted into the 7:30s, stop at 14. Never 16 this week.
