Yes, I still run! There are three elements to running that focusing on will separate a novice from a seasoned runner
1. Breathing
Try to stay relaxed while you run, I take long breathes in through my nose and out through my mouth (it becomes harder and harder to do as you get more tired)
I also run with a little radio and headphones, it takes my mind off the fact that I’m running and I’m able to control my breathing better

2. Shoes
If you’re serious about running, you should be serious about your feet. I get new running shoes about ever 4 to 5 months. My preferred brand is New Balance.
3. Stride
Perfecting a running stride can take awhile and there’s tons of stuff online about it – my only advice is not to make fists while you run, I keep my hands at ease, it’s part of that whole ‘relaxed’ concept. Another thing to focus on is keeping your head level, it shouldn’t bounce up and down while you run.
Start out slow and don't expect great things unless you run AT LEAST three times a week. Another thing, spare your knees, run on trails, not road!
