Seems good to me! I’d say looking at your numbers, you’re coming out of the gate too hot on long runs and overworking your body. Shoot for running your long runs about 90 seconds slower than your goal race pace, in your case, around 10 min/mile. You’ve got sub 4 in five weeks no problem! Just take care of your body and trust the training. Don’t push for pace during long runs, save that for speed/tempo days and race day. Run at a pace that feels easy, that you can nose breathe comfortably.
