So, today at school(writing this on my phone during recess btw) our form teacher told us that we are going to run 1 mile(thats 10 km) in about 2 weeks. Now the problem is that I'm kinda out off shape(not overweight though) and I think that I would be able to run 3-4 km, which is'nt really good enough. So, any tips on how to quickly get in somewhat better shape and at least be able to run 5 km? I'm already taking a daily jog. EDIT: It would appear that my math teacher is kinda bad, with metric mile I meant 10 km.
