I used to HATE running because of school PE, too. When I first started running, I couldn't even run for 30 seconds without feeling like I was dying! My throat would burn, I felt like I wasn't getting enough air, my legs were tired, etc.
But every day, I would go for a "walk" and then try to make little goals for myself, like "lightly jog to the street sign." And each day, I would build onto that, so that I was running further & further each day.
I have been running daily since April of this year, and now I can run for about 15 minutes at a time. (I don't track miles, only minutes) Which doesn't sound like much, but considering how bad my teachers would complain that my cardio was when I was a kid, it's a major feat for me!
I plug in my iPod and zone out! I love it, now! I still can't run long distances, I usually run for as long as I can until i feel breathless and then I slow to a walk until I feel I can run again. But long-distance, steady running is the type that strengthens your heart; whereas the interval running that I do helps burn fat. (Which is why I run, anyways, so it works out great for me!)
And I had every problem in the book when I first started! I got plantar faciitis in my feet from not having enough cushioning for my heels. I had shin splints, I had pulled muscles, etc. I've finally figured out a delicate balance so I can keep everything just right. ๐
Moral of the story: BUY GOOD RUNNING SHOES and make sure that they are cushioned properly! And learn good running form. You'll avoid all those painful mistakes new runners often make.
Good luck! ๐
