This is a fantastic article from Runners World about BEGINNING to RUN or coming back from a long break.
In particular, I like Karen Goucher's GETTING STARTED TIPS:
GETTING STARTED
Talk It Through
New runners think it's not "real" running unless you're gasping for breath. Not true. If you can't talk, slow down.
Take Pride
A lot of people think they look slow, or fat, or sweaty. Don't let any of that stop you. Among runners, you are golden.
Make It a Habit
Run two, three, or four days a week, and don't worry too much about how far or how long you run. You want to get used to being active for several days each week.
Think Rest Day
Instead of saying, "I'm going to run three days this week," say, "I'm going to give myself at least three rest days this week." The ol' reverse psychology—it works!
Mix It Up
Vary the places and surfaces where you run so that you spread the physical stresses around evenly.
Be Flexible
Many runners are afraid to deviate from their training plans. But I think having fun is more important. Never be afraid to do the run you feel like doing if the one on your schedule isn't going to cut it.
Reward Yourself
Whatever resonates for you as an incentive to run—a second glass of wine? sleeping in?—do it at the end of each week.
Find a Mentor
For many runners, a mentor works better than a coach. Find one by joining a group of training friends, a running club, or the group that meets at a running store.
