Unfortunately, you can't blame your short legs. It has to do with just how quick your legs "turn over". It happens to tall people too. I just completed my first 1/2 marathon in February. Last summer I was at that speed too. Speed comes in time. Do the speed that works for you. Don't worry about the speed they say. Interval training with sprints will eventually bring your speed up, but I'm guessing your goal right now is distance. My motto is anything faster than a walk is a jog and is good.
I strongly recommend that you join The Rookie Running Group on SparkPeople. It's full of new runners like us and a ton of experienced runners that love to help and answer questions.
Don't worry about your speed it will definitely come in time. Running is a life time sport.
Congrats on your achievements!!
