Should i build leg muscle for a 4k race?

For a 4k you should worry more about cardio. Running should help you build stronger lungs, rather than strong legs, which are less important.

Answer 2

it wouldnt hurt to

Answer 3

It could only help, and in the process of stronger legs, you achieve cardio, which is even more important. You ever see the Rocky movies? If you want leg and cardio run up bleachers, or stairs, or something of that effect, which will really get your heart working.

Answer 4

Yes especially if you are young. A great way of doing this is to run up hills and stairs.
