I am a runner. I train at what is probably the 80th percentile for longer distances, so I am by no means an expert. But I do understand that if you are running 7 miles a week, most of the time, your body isn’t going to be that beat up, especially if you are taking it slow.
Most people sit at a desk for 40 hrs a week. That is way more damaging to your health.
I take ~2 mile brisk walks every day (the kind where my pulse will average to 130), interspersed with casual multi-mile hikes up the mountain trail nearby. That’s just my baseline cardio and movement to feel good and keep myself healthy.
If my heart rate is 130, that's a run for me, all be ot slow. 33-35min ish 5k.
A brisk walk would be 95ish
However, the cardio should help. With overall health that is, not whatever blown knee or hip or whatever he'll have to deal with later.
You should not conclude from that, that it is healthy for every person to do so.

If that game helps, fine.
finally when they had to (successfully) defib him during a race, that shook him into assessing his health not running for the sake of running
There's a mindset with distance runners that I have seen over and over, just sometimes way too much of a generally good thing
