For long distances quite alot is down to the genetics of the runner, see how they are all identical builds.
There's nothing stopping you, get yourself onto a marathon training program, sure there is numerous on here, and just crack on with it!
Well i'm 20 and i'm hoping on joining an elite branch of the military, not a dedicated runner but im a complete all-rounder.
For 10K i'm onyl hitting 43 minutes so dont worry too much at the minute about your times. keep up the training and you will be a promising young athlete in years to come.
Good to see some dedication from someone at such a young age.
I always use Nike+ GPS app, but have some issues regarding its reliablility.
Each upgrade seems to deteriorate its quality ironically.
But i'm too afraid to lose my accumulated miles
Firstly, thats a great time for your age!
You will find your time decrese as you mature and grow, expect to be hitting 18 mins by age 19!!
