The question, read
You already own the answer; it is in the log you keep. Four reads of it separate a block that is working from one that only feels busy. None of them need a coach. Here is each one, and what a good result looks like.
A single big week means little; the eight-week shape means a lot. Sound training rises for two or three weeks, then takes a lighter week, then rises again — a sawtooth, not a staircase.
The two honest failures are visible from the shape alone. Weeks that only go up, with no down week in two months, are the common path to a long plateau or a forced layoff. Weeks that never rise at all mean you are training to stay the same.
The read that changes minds most often. Sort your runs by honest effort and look at the gap between easy days and hard days. In a working block that gap is wide — 45 to 60 seconds a kilometre or more.
When everything sits in one narrow band, easy days are too hard to absorb and hard days are too tired to be fast. That is the grey zone, and it is why a block can feel diligent for months and produce nothing. Slowing the easy runs is the cheapest speed there is.
Clock pace misleads, because effort moves. The fair comparison is the same route, or the same heart rate, weeks apart. If 5:35 a kilometre felt like a real effort eight weeks ago, and now sits easily inside an easy run, you are fitter.
Strava's graphs will plot both runs. The pairing — same effort, different weeks — is the part they cannot do.
Missed weeks are not a moral failure; they are a cost you can price. Two weeks nearly off costs about ten days of fitness. That is why the block after a layoff should not resume where the last one ended.
The read that matters: four runs a week for eight weeks beats six runs for two weeks and none for one, every time. Whatever the volume, the sawtooth of a steady week repeated is the shape that carries a runner to a start line.
Read volume for the shape, easy runs for the gap, paired efforts for the trend, and the calendar for the gaps. If all four look right, the block is working and the clock will confirm it within weeks.
Reading all four honestly takes an evening with a spreadsheet — or about a minute, if someone reads the block for you and shows their evidence.
