I can run 1500m race. That is quite long. What about you
I'm not good at long distance or endurance running. 
Wow, its a form of exercise, you need to try it you know
I know running is aerobic and requires stamina as well as mental strength. I just don't enjoy it.
Wow. So what exercise do you enjoy doing ?
I like walking around the park but nothing strenuous. Long distance running can also improve cardiovascular health.
Long distance running helps to circulate blood properly. It is very good for the body
It also increases activity of enzymes and hormones that stimulate the muscles and heart.
