A good runner at my club has been doing RED Jan (Run Every Day). I don't know him well, he's much quicker than me and obviously, haven't seen him in ages, but I see his FB posts.
He's "only" doing 5k per day and is finding it really hard. Had to walk parts of his run today. Which is all perfectly normal for most people, running every day is tough (and not really to be recommended) but this is a young man who was marathon fit in November and used to running most days, for much longer distances. I'm really surprised he's finding it so hard.
I was thinking of messaging him and asking after his health, maybe suggests he sees doctor, lots of health issues show up first in our running.
I mean it out of genuine concern, but none of my business?
