You Know You're a Runner When...

when you've run, showered, and eaten breakfast (twice) before your family/roommates even wake up.
when your family knows that you will run on Thanksgiving and Christmas (or other holidays you celebrate) no matter what.
when your friends no longer look at you like you're nuts because they know it for sure.
when you forget birthdays and anniversaries, even major holidays, but never the date of your next race.
when you have to make a real effort to remember to talk to your (non-running) family and friends about something other than running.
when your family plans vacations based on where your next marathon will be.
when your non-running family and friends know the differences between feet that are neutral, over-pronating, and supinating.
when you run so much that your family has a separate laundry basket for your running clothes.
when people stop asking you if you are going to run today, but rather ask you when.
when you tell people you ran a 10k and you are shocked that people think that is a long run.
when you call four miles an easy day.
when you try to convince people to run a 5k because it's "only" three miles.
when you no longer have to explain to your friends why cotton isn't the best choice for running attire.
when you come back after an hour-long run and your spouse says, "That was fast. I didn't expect you back so soon."
when you smirk at people who tell you that you run too much or are crazy for enjoying a run.
