Running is now a social activity.  If you aren't doing it already, its time to socialize your running game.
So how can you get started?

"That which does not kill us, makes us stronger.” - Friedrich Nietzsche

Apparently Nietzsche got something right: overcoming challenges does make you stronger. Scientists and psychologists have conducted studies that prove austerity increases strength,  and adaptability. 
The race training process is a perfect example of how challenges push us to our limits, and ultimately make us tougher and durable.
But to any one who has run in any race, from a 5K to a Full Marathon already know this to be true, 
Running is hard. Building up stamina and endurance is hard. Running 11 miles in February may not be the most fun activity. But what not all runners realize, is that the challenge actually improves the entire running experience. The higher the goal, the higher the reward. More so than that, without any difficulty, the running experience is less meaningful and a lot less enjoyable.
