I am a super fast long distance runner where I run at a minimum of five miles!
This is exciting. How fast do you usually run?
I actually haven't checked my time, I just do it for cardiovascular health. 
You know running is best for maininting good cardiovascular health.
It does so much! Like increasing the activity of enzymes and hormones to make the heart work better.
Yes, and it also reduced the chaces of heart attacks later in the life
The military also uses running as a form of physical training.
