Monday hill workout

Tonight called for 16 hill repeats on "Yugo" Hill near the Lindbergh Center. The distance up the hill is 0.11 miles. I wanted to run up to the top at a tough pace, and have my first rep be as strong/fast as my last.
Here are the splits:
1 - 47.7 seconds
2 - 48.1
3 - 47.1
4 - 47.1
5 - 47.1
6 - 50.0
7 - 46.3
8 - 46.0
9 - 44.9
10 - 44.9
11 - 45.2
12 - 44.7
13 - 44.0
14 - 43.7
15 - 43.8
16 - 41.1
Felt great at the end, but winded. Felt like I gave it my all, and I was pretty surprised I could keep that effort/speed up the whole time.
