I agree that isolating your real goal is important to deciding how to adjust these workouts. Are you just throwing everything at your training in the hopes that some of it will stick or do you have something you need to focus on for your goals?
I would go completely the other way here and say, no, that is not feasible. I would not put those back to back. In fact I would add more easy days to your schedule. Most workout types stay in your body and make relevant adaptations for longer than just a week. You don't need to keep doing the same several workouts every week. Do a long run every other week and just have good volume otherwise. Do intervals or a tempo every other week and just add strides or hill sprints on some easy days.
Without sounding like I'm a know-it-all or that what you're doing is wrong, let me refocus my thought. I don't think you need to look at your training in terms of an arbitrary 7 day week, let alone a repeating pattern of it. Training works through appropriate stresses and healthy adaptations. Many people will tell you that a schedule with a harder day followed by two easier days allows for better workouts and better recovery.
Specifically with a long run you are looking at stress to your nervous system, fueling system, and repetitive stress to muscoskeletal system. Fueling can be handled with a healthy diet. The muscoskeletal thing is mostly dependent on your body's response to the specific day, but delayed onset muscle soreness can hit you like a truck a couple of days later especially if you do a hard workout the day before or after a long run. The nervous system thing is perhaps the biggest deal, as your body will be inclined toward a state of recovery following a long run. You put unnecessary stress on that recovery by doing hard workouts surrounding it. Basically you are getting less out of the long run and putting more injurious stress on your body by jamming this stuff together.
Some of the best coaching advice I can give you is that feeling compelled to force workouts into close proximity is a sign of insecurity or lack of confidence in your own ability. The solution there is not always to run more. Have more confidence in your ability to take a day off or incorporate easy days. Things like red blood cells last 3 months. Your block of training is more important than a specific few days, especially if you risk injury. Speed has more to do with mechanical adaptations than frequency of doing them. Do them correctly when you do them and worry less about doing them all the time. There is plenty of science to support more recovery if faith in yourself isn't enough for you.
