I've run some half marathons and concluded that long distance running is the worst exercise. It's very repetitive, takes tons of time, messes up your feet, messes up your back, makes your body economical so you'll forever have a harder time losing weight, and on top of that it makes you lose muscle, professional long distance runners look like thin-armed freaks.

Do some strength training and some playful sport instead, like basketball or BJJ. It's fun, you'll look good, you'll move well, and you'll get confident with people, all in 2-4 hours per week.
