i am still trying to increase my running skill 
Wow, that will be great, i will suggest you get some exercise machines especially treadmill
yeah it is a great idea to increase the skill 
I believe for as low as 900 dollars you can see a product that can help your skills. treadmills that have reasonable ratings can also be seen for around 600 dollars
it is not so much expensive
And since you have a good health you can always exploit your options in running, and probably register for competitions
