7k to work today. Usually try to avoid running fast since I prefer distance over pace but had a go yesterday home from work, really pleased as never been sub40 on 10k before and this was with a 3kg+ backpack.
Tried out my field of computer science a couple of months, sucked ass. Reassessed what I wanted to do and went to advertising, loved it and been there ever since. If you have a good academic background you can do whatever. Do what you love.
