Run with a Buddy (or Several)
Running isn't usually a team sport, but that doesn't mean that you won't want to be around other runners. For most of us, a daily running partner isn't practical unless your significant other or best running pal has the exact same schedule. But running with a friend once or twice a week keeps you honest. It adds a little more guilt when you decide that sleeping in or sipping on a glass of wine seems more appealing than hitting the trail.
Take social running a step further by joining a running club. You're more likely to keep it up if you're around others driving toward the same objective. Submerge yourself in a running community by planning activities around your runs. Plan a weekend morning run followed by brunch, or celebrate a jog in the afternoon with happy hour. Frequent your local running store and meet other runners. Running store owners and employees usually have a genuine passion for the sport and are ideal motivators.
