I run. I have been running for a long time. But my diminutive stature compared to most of the people my age has never been a major hinderance to my running. I continue to run despite the perceived disadvantage of having to take more steps. In fact, there are many cases where I am faster than those who are taller than me.
What astonished me however is that this can also be applied to an international setting. At just 5 feet and 5 inches, Leonel Manzano would appear to have a distinct disadvantage to all of his taller counterparts. However, this has not slowed down his running or made his results any worse. In fact, he’s beating many of his opponents. True, he has the benefit of physical conditions (a bigger heart and lower consumption of oxygen), but it goes to show that you can never judge a book by its cover. Just because one is small doesn’t mean one is incapable of brilliant things.
