FAQ:
>Can I run if I'm fat?
Yes, but it depends on height/weight/age/experience/prior injuries.
>Where do I start?
c25k (couch to 5 kilometers)
>What then?
Depends on your goals.
>I don't have any running goals, I just want to stay reasonably fit, what do?
Do cardio at least twice a week for 30-60min. No need for speedwork then.
>Will I lose all my gains?
No.
>Will I lose weight?
Maybe, depends on CICO.
>Can I do cardio on rest days?
Yes, stick to easy runs.
>Does running kill my [bodypart]?
No. Feel free to ask for the pasta with the studies.
>Why does my [bodypart] hurt?
Check your form, equipment, schedule. You might be old, overweight or a noob. Ask again, give more information.
>How do I improve my time over distance [distance]?
Probably more weekly miles. Maybe speedwork. You'd best stick to a plan. Either read Jack Daniels (highly recommended) or google for 'sub [time] [distance]', chose one of the plans and ask if it's any good. If it contains 4-7 days of running, 1-2 speedwork and 1 longrun it's probably alright.
>What shoes should I buy?
Depends on your terrain, weekly milage, weight etc.. In general all brands produce quality products. Read:

>What other equipment should I buy?
The most important data to control your training is probably heart rate and then pace. You best get a cheap garmin forerunner (or equivalent), so you can watch both during your run. A HR strap for your phone can do the trick, if you are short on money.
>Should I lift?
Yes, you want a strong core and legs. Diddies, Squats, Lunges, Trap Bar Diddies and core work. Depends on goals, schedule etc.
>What else should I know?
You are probably running too fast.
>What else should I do?
Partake in local 5k's,10k's and half marathons. They are fun, even if you are slow.
