Intervals: 6 Sets by I K @ 4:30/K Pace With 20-Minute Jog Before and After It

I did intervals tonight. They are usually scheduled on Thursday night. It was Thursday yesterday, but I went out for a drink at night because it was the night before a hour-day holiday, so I skipped running training. Today I made up for it. The result is shown below:
1st Set: 4:26.17
Jog: 1:00.17
2nd Set: 4:25.23
Jog: 1:00.18
3rd Set: 4:28.90
Jog: 1:00.21
4th Set: 4:23.19
Jog: 1:00.24
5th Set: 4:26.25
Jog: 1:00.30
6th Set: 4:31.53
Total: 31:42.37

I ran in split-toe minimalist shoes MUTEKI. 

I jogged 20 minutes before and after the intervals to warm up and warm down respectively.  

I also did high intensity cardio using an old car tire in the afternoon tonight.
