A training plan that is unplanned?

Going by feel can work. When I've been coached in the past, I've never known what to do when assigned a particular workout your body just tells you on the day you are not ready for. Then the whole program gets thrown off.

Some people have done really well w a program where they abide by the rule when you are feeling good always go hard. when not take it easy or keep anything hard very short

The tweak you should make is actually training in a progressive manner. If you aren't doing more you need to actually try getting faster.

People will do months of the same stuff and be in about the same shape when they are done as they were after the first month.

What you are doing all sounds fairly conventional and should be pretty effective for maintaining a general degree of running fitness and keep you race ready across a pretty broad range of races.

Personally, I like to start with the end in mind and plan out a training cycle with a fair degree of specificity. I think this is important if you have a goal race in mind, plus it generally keeps me honest.

The other benefit of this approach is that it formally incorporates periodization. I think periodization is important not only to bring you to a peak, but also because it usually results in a planned break at the end of a training cycle and it also usually results in emphasizing and de-emphasizing certain training stimuli during the training cycle. The change in emphasis over time prevents your body from getting so use to experiencing the same stimulus on such a consistent basis that it no longer continues to adapt.

All of that can also be accomplished with your approach as well, and it would not surprise me if you were actually doing this to some degree already, either consciously or subconsciously ("I have a race in a couple of weeks, so I am going to start backing down on some of the long hard intervals and work a little shorter speed stuff for the next couple of workouts."). But I prefer to plan out my workouts pretty far in advance and then adapt to circumstances ("It is way to hot for mile repeats today, so I am going to cut it down to 1000s." "My legs are more beat up from my long than I expected, so I am going to skip the 400s at mile pace, but I will add in some strides after my easy distance.").

I double 4-5 times a day...

Should I put more thought into planning runs/workouts? What tweaks should be made?

Yes. You only need to double once a day. With your 8-10 runs a day, you likely aren't going long enough on each one to get any benefit.

Oops, by day I mean week haha.

In response to other posters, I do plan to adjust workouts and vary volume once the track meets start to roll around. What I originally described is primarily for my base phase.
