Runners over 40 do not need to be told to care about mileage.
They already do.
The missing piece is usually strength context. Not because strength is new, but because it is still treated as a side quest instead of part of the weekly load.
That is a mistake.
For masters runners, strength work can protect tissue, improve economy and keep the athlete training. It can also wreck a run week if it is placed badly.
Both things are true.
Mileage Alone Is Too Narrow
A runner can hit every planned kilometre and still move backward.
Maybe the easy runs are drifting higher in heart rate. Maybe the calves are tight after speed. Maybe sleep drops after late sessions. Maybe the athlete adds gym work but never adjusts the running week.
The watch sees kilometres.
The body feels the whole week.
That difference matters more with age because recovery gaps are less forgiving. The athlete can still train hard, but the margin for messy placement gets smaller.
Strength Needs To Be In The Report
Strength training should not sit outside the performance review.
A useful weekly report should ask whether lifting helped or hurt the run week.
Did heavy legs land too close to intervals? Did the athlete keep enough strength work during higher mileage? Did soreness change stride or cadence? Did hill work and gym work stack the same tissue stress? Did the long run suffer because the week was already too dense?
That is the level athletes actually need.
Not more guilt about lifting.
Better placement.
The Practical Rule
For many runners over 40, the first rule is simple.
Protect the key run. Protect one strength session. Do not let every other session fight those two priorities.
Some weeks that means lifting lighter. Some weeks it means moving intensity. Some weeks it means cutting junk mileage. Some weeks it means accepting that the best long term move is boring.
That is not a motivational problem.
It is a decision problem.
The P247 View
P247 should help masters runners see the whole week.
Mileage, strength, recovery, sleep, soreness, life stress and the next key session need to sit in one report.
The goal is not to make the runner cautious. The goal is to keep them consistent enough to build.
You already have the data. P247 tells you what to do next.

1/ Runners over 40 do not just need mileage data.
2/ They need strength and recovery context beside it.
3/ A good gym session can protect the runner.
4/ A badly placed gym session can wreck the week.
5/ The useful answer is not more data. It is better weekly placement.
Green score. Destroyed legs. There are blind spots in your wearable data. P247 is being built to connect the numbers with what actually happened.
