I love running in marathons.
You mean distance running? as in,  aerobic in nature and requires stamina as well as mental strength.
Yes, it is a lot of fun. Do you know how far people have to run in marathons?
Yeah, I myself haven't done a marathon but I have done a half marathon road race.
That is really impressive though!
Yeah I mainly run as a means to improve my cardiovascular health.
That is really important as it can lead to a longer life.
Yeah endurance running is often also a component of military training.
That is true, they have to stay in really good shape.
Yeah it is amazing what happens to the body when you run, activity of enzymes and hormones that stimulate the muscles and the heart to work more efficiently.
