Outside Run

So I made my first run outside in a long time today...ran the "Rail Trail."  From beginning to end its 2 miles..but then if you turn around and come back its 4 miles...I think?

Anyway, the last time I ran a down and back on the Rail Trail, my run looked like this on Nov. 19th:
4.02 miles / 33:18 time / 8:17 pace

Today, I am pretty sure I was running against the wind for all 4 miles...and I am sure the whole run was uphill.
Here is what I did today on my run:
4.0 miles / 29:18 time / 7:20 pace

I think I am a little faster...
