4x1200m Speed Workout -- Pace around 7:17

I setup the workout a little bit wrong. The warm up and cool
down should be 1.5 miles. And There should not be a rest
and recovery after the last repeats. Here is the setup I had
on Garmin:

1. Warm Up 2 mi None
2. Rest 3:00 min:sec None
3. Repeat 4 Times

   1. Interval 0.75 mi None
   2. Recovery 0.38 mi None
4. Rest 3:00 min:sec None
5. Cool Down 2 mi None

It was a little bit slow than I expected, partly because of the blister
pain on the bottom of the left foot. Also, it's my first speed workout by myself.
Here are the splits:

Split	Time	Distance	Avg Pace
Summary	1:16:38.0	8.77	8:44
1	17:12.6	2.00	8:36
2	3:00.0	0.15	19:38
3	5:10.7	0.75	6:54
4	3:23.1	0.38	8:54
5	5:22.2	0.75	7:10
6	3:29.6	0.38	9:11
7	5:27.9	0.75	7:17
8	3:28.5	0.38	9:08
9	5:27.0	0.75	7:16
10	3:54.1	0.38	10:16
11	3:00.0	0.09	32:27
12	17:42.8	2.00	8:51

The lap 2 & 11 are 3 minutes rest(I should delete it in the future).
And the Lap 10 of 0.375 mile(600m) recovery should be removed
as well. This is not necessary.

Coach asked me to run Pace 6:47 to 7:05 if my half M goal is 1:37.
Or 6:56 to 7:13 if my half M goal is 1;39. May need try a little bit harder
next time.
