Monday easy run 8 miles

Just want to run easy so that I can have enough energy to run
5X1 miles tomorrow. I just want to check whether I can run the
5 miles with pace around 6:50 to 7:20. Here are the splits for this morning:

Split	Time	Distance	Avg Pace
Summary	1:10:15.5	8.00	8:47
1	9:21.7	1.00	9:22
2	9:25.5	1.00	9:25
3	8:58.8	1.00	8:59
4	8:55.2	1.00	8:55
5	8:20.1	1.00	8:20
6	8:21.7	1.00	8:22

Completed the book of Hear Rate monitor for dummies. The only thing

I can remember is that I should run easy run easily.
