StarvingMartistRecently started jogging 30 minutes twice a week. When does it stop feeling like I'm dying?
If you went from nothing to 30 minute jogs, likely a little while. What’s your history? Solid couch potato with a potato shaped body or worse? You’re looking at a couple hard months. Formerly fit/fit-ish, maybe some high school sports or something? Maybe an unpleasant month or so. You’d be better off easing into it a little slower. Can you do a brisk walk for 30+ minutes? Jog for 10-15? Build up to a full 30 minute jog. They have things like C25K (Couch to 5K) programs that give you good pacing.
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.
