You're a runner if...

... you have hundreds of safety pins scattered around your house
... you love running in the rain
… you can say “runner’s nipple” in mixed company
... you carry a water-bottle everywhere
... you double knot all your shoes out of habit
... you have a watch tan that never goes away
... you feel naked without your stopwatch on
... you pack a separate bag for your running clothes
... pasta is the only food you'll eat for two nights before a race
... you try to convince people to run a 5k because it's "only 3 miles”
