Awesome! If you can keep up something lime this consistently you will see a lot of improvement.
That being said, I’ll nitpick about some things about your schedule that will help you:
Sunday - Your long run looks fine.
Monday - Tempo looks good, but if you could switch Monday and Tuesday, then your legs will be fresher going into the tempo.
Tuesday - 10k easy could be reduced, but could be okay.
Wednesday - This is good to take it easy since you plan to do a workout the next day.
Thursday - Looks good since it’s the beginning of your training plan. You should try to increase the total distance of the intervals as you progress. Maybe try 5x400 or 10x200 with one minute rest next week. How long is the rest or recovery between reps?
Thursday - Nice: Easy and not too long.
Friday - This seems like too much, but you seem to know that already. Also, a 7:40 mile seems like a time trial/race effort. Threshold has different definitions, but it would be a pace that you could maintain for at least 30 minutes.
Saturday - Good.
How do you feel after that week? Listen to your body and cut back if you feel like you need to. Eliminate the third hard day, and as you go forward aim to focus on the two hard days. Increase the distance of the tempo as you go forward. You have room to cut back (reduce the long run to one hour, reduce the Tuesday/Monday 10k) that would help you recover better between the hard days. If you keep up a schedule like this and try another mile TT in a month or so, you should see a nice improvement.
