8 Mile Tempo with pace around 7:40(Ttal 10 miles Avg Pace 7:54)

Sometimes I just felt that I could not run faster. That's what happened
for the first 2 miles. And even mile 3 & 4 was still slower than expected.
But I could not do much about it. Sometimes, I just thought maybe I
can run better after 7am?

I think the muscle warmed up enough after mile 4. Then I have a steady
finish with the paces around 7:40, with the fastest last mile pace 7:35.
My stride lender is still 1.09m. I know I could run better if my stride length
can even increased a few CMs.

Here are the splits:
