Everything about fitness is very personal. Your running speed and my running speed won't be the same. You may never run a fast mile, but you know what, who cares? It's OK to be slow as long as you're moving. I'm pretty sure there are people who can walk a mile faster than I can run one, but I don't pretend to like running or even be good at it. But I know that movement is good for my body, so I get out there and do what I can.
Don't get discouraged if running is hard for you. Maybe you'll try it for awhile and realize you just don't want to work out that way. Fine! Find a workout that works for you. But running is one of the easiest ways to work out with no gym and no equipment, so it's a good one to have in your back pocket if you decide you're itching to break a sweat some day.
