run is important for all sports

no, i just walk fast as i can. hehehehhe

I've been watching Coach Carter a lot every time it comes on cable these days, and on that show, the coach makes his athletes do a lot of running, because they have to run on the basketball court during games. It's part of their training. In football (and American football,) a lot of running is involved, in tennis, cricket, netball, baseball...seems like a lot of sports require running, so I think you are right...I can think of maybe one or two that don't require running, like maybe cycling! But as a fitness tool, I believe even cyclists would probably take to the track and put in some quality time. And of course there are those who run to gain speed, fitness and endurance to win long races like 5K, 10K and marathons etc. I don't know if I would ever try to run a marathon, but I have run a half-marathon and I can tell you it's just 6 miles too long! But I run 5K races all the time and I think I will continue because they are just long enough to be a challenge and short enough not to wear me out or bore me with the monotony of it! It's a sport in its own right and a great fitness tool. I heard somewhere that it's supposed to be a really good way to lose weight, but I don't know if that has been scientifically proven yet.

i think running is a sport and hard to do for a long time so i walk

It almost involved in many sports. You can see it in football, tennis, cricket, basket ball. It is a part in almost all the games.
