Run Goal: Fast 2km

I walked down to the C wall - set my nike+ to 2km and tried to run fast. I was winded at the end.. and you can see I really slowed down at the end.. maybe I should have tried to pace myself at the beginning. I prefer to run long and slow. I am not hurting at all though - which happens after the long runs. I should do more of these short runs... I have joined a challenge for fast 2kms and fast 6kms... on the nikeplus site. I am not winning but there are people who are the same as me.. so that is cool.
