Midnight Mixed K's in "Jikatabi"

I did mixed K's after coming home from work. I did them in jikatabi split-toe sock-like shoes favored by traditional Japanese construction workers. 

The first K was run at my full marathon pace. I then took a short rest of 30 seconds. In the second K I ran at my half-marathon pace, slightly faster than the first K. When it's done, the rest was slightly longer: one minute. Then in the 3rd K I ran at my 10 K pace. The rest after that was extended to a minute and a half. The fourth K is sit'n kick K, which means you start off at a comfortable pace, but then in the last two hundred meters or so, you kick to the finish. The rest after this is the longest: two minutes. This is one set. I did it two sets. 

The result is shown below:

1st K: 4:39.80

Rest: 30.32

2nd K: 4:21.09

Rest: 1:00.33

3rd K: 3:53.10

Rest: 1:30.33

4th K: 4:19.80

Rest: 2:00.34

5th K: 5:05.59

Rest: 30.39

6th K: 4:29.11

Rest: 1.00.38

7th K: 4:06.17

Rest: 1:30.20

8th K: 4:45.20

Total 8 K: 43.42.15

I like mixed K's because I like the gradual pressure building within myself as I go through the sets, steadily increasing the pace. The brief rest that comes after each K is a bliss. You can easily reset your motivation. Also, as you change the pace, different systems of your body seem to get to be activated. So it's good to prepare your body for strategic changing of pace. I recommend you to try it when you get tired of a long, slow run. It's also recommendable for those who find regular interval training a little too challenging.
