Depends on your goals. Also depends on you.
Running all day imo is an easy way to lose weight and train yourself for endurance runs. Very boring so definitely get some music/podcasts/audiobooks.
Bunch of crunches and pushups everyday won't focus much so it is just an overall minor health boost. Oh and I see you said sit-ups, which can lead to back problems if you do too many. Crunches on the other hand afaik are much safer.
So overall your plan is limited, but if that is what it takes then go for it.
