Very good 7.1 mile "Pace Run"

Today I was to do between 6 and 8 miles -- 1 warmup mile and the rest at marathon pace. The route I picked was 7.1 miles (11.4 km).

I sort of screwed up my GPS, so I didn't know exactly where my first mile was done, but I guessed and then did 10 kilometres (6.125 miles) at pace. Here are my kilometre splits:

4:58
4:59
5:00
4:54
4:59
4:59
4:57
4:57
4:54
4:57

Average of 4:57.4

I'm supposed to do 4:55.7 per km to reach my goal of 3:28 -- so these times are definitely in range. Just have to do it for 4.2 times as long! :-)
