I've been running for years, (4) years to be exact. I can't only run a mile in seven minutes. I train and practice, I don't smoke and I'm not overweight. I have to run the mile downhill to get seven minutes, otherwise its slower if I do it on a flat surface. I'm twenty yr old male, run 20-30 miles per week but that's all I can handle. Why can't I run?

some people don't have a "running build" but in your case, I think that you aren't pushing yourself. It's all mental, if you have a pain in your legs it means you're working. Try running with a group because they will always go slightly faster every day to beat the other people without knowing it. Hope this helps

Some people just aren't really meant to run, if you know what I mean.
