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.
