Speed workout 3 minutes fast and 3 minutes recovery for 5x1k

We did 5 loops around the community park with all out
3 minutes fast. And then walk or jog for another 3 minutes.
Rest for 1.5 minutes. I think I can keep this here so that
I can know how to train myself next time.

I ran a little bit slow recently. According to my friend,
I am not at hot hands. I think, that's because the training
is after 6pm, and it is already dark. And usually even though
I wear the headlamp, I do not run fast in the dark.

Anyway, I still have enough time to build the base.
I was thinking about to swim soon, and have regular biking.
I need to exercise the upper part of my ody. It is so weak,
compared to the legs, and lower part.

Here are the splits, though not useful:

Split	Time	Distance	Avg Pace
Summary	44:54.2	5.39	8:19
1	8:35.6	1.00	8:36
2	7:33.5	1.00	7:33
3	8:18.1	1.00	8:18
4	8:03.4	1.00	8:03
5	8:47.4	1.00	8:47
6	3:36.2	0.39	9:0

I did notice some pace of 6:45, but it is indeed useless when 

it is about only half a mile, and then rest.
