Hey, Sunny D. There are lots of programs you can use and follow to train. There's the runner's world link above, there is also Hal Higdon, Jeff Galloway, Couth to 5K. Do a google search on any of these things and you'll find them very easily.
YOU CAN DO IT! Believe me...I am not a runner, although I just ran my first-ever marathon this past January. I am not a runner! LOL. I'm starting to feel like one, though, and so can you. I LOVE IT NOW and am totally addicted. You will get lots of advice from ladies on this forum that know WAY MORE than I do about running!
The best way to learn to run that distance, is to slowly run that distance...work your way up to that mileage. ALl the programs you'll see will guide you!
GOOD LUCK!
Gayle
