I work in the trades, constantly pushing 400lbs crates on wheels, I’m not unfit, but I wouldn’t say I’m running fit. It’s like a whole new part of my feet and legs just gives out while other parts can keep going
That’s the SAID (specific adaptation to imposed demand) principle at work. You’ve gotten used the movements you do every day and your muscles can perform them more efficiently. The same will eventually happen with running, once you’ve been doing it long enough for it to not feel like a new movement. Keep at it.
