Eric Yerman Memorial 5K Run 33'19"

I participated Eric Yerman Memorial 5K Run & Family Walk to Benefit Friends of Children yesterday and the result is disappointed. I wear number 181, and the result is here. My wish is to run into 32', but I failed to do it. I was pretty comfortable with the pace before hitting a hill in 1.1 mile. I started to walk from there. I should not have started to walk that early. I planned to walk after at least 2 mile and better to run the whole distance without walk. I will try to run without walk next time, even I run slower, but no walk.
I feel I start (or restart?) to love running more than lose weight. At the beginning, I run to lose weight, but now I want to lose some weight to run faster. I am trying to lose 2-3 lbs before Oct. 6th run. I have not decided yet which run to register, one is a 4 miler and another one is another 5k, I think the 5k will be the same route as this one. 4 miler is more challenge and best of all, much cheaper, hehe.
