YOU MIGHT BE A RUNNER IF... You have more old dirty shoes piled by the front door than a farmer. You read each month’s issue of Runner’s World cover to cover within 24 hours. You get excited when you hear there’s a new Gel flavor. You’re not embarrassed to show somebody where your hamstring really hurts. You drive by a golf course and think about what a great place it would be to run. You can remember your time from a marathon eight years ago but forget your mother-in-law’s birthday. Hearing the soundtrack to "Rocky" gives you goose bumps. You wear a black, plastic sports watch with your dress clothes. You know that there’s no such thing as too much pasta. You know you are getting in good shape when you have to tighten your belt. Your friends know to never call you after 8:30 at night. You get up earlier on the weekends to run than you do during the week for work. You think the inventor of PowerBars should have his likeness engraved at Mt. Rushmore. You have hundreds of safety pins scattered around your house. You have more T-shirts than a souvenir stop. You’d stand in line for Bill Rodgers’ autograph. You won’t drive by any running store without a quick look inside. You install hooks in your shower for wet running clothes. You weigh less now than you did in high school. You can’t wait for the next birthday you move into a new age group. OR, YOU MIGHT BE A JOGGER IF. . . Your running shoes came from any store that also sells food or diapers. The only marathons you’ve heard of are in Boston and New York. You think cotton is the best fabric for athletic gear. You think fartlek is an embarrassing result of Mexican food. (It’s a Swedish term for a type of interval workout.) You have no idea how far a kilometer is. When someone asks you your PR, you don’t know what they mean. You do not spend at least 33 percent of your annual income in a local running store. You don’t know what Gore-Tex AE is and you don’t care. You think splits are something only cheerleaders care about. You think endorphins are the latest must-have children’s toy. You enter a race and don’t know where to pin your race number. You worry that another plate of pasta might be too much. You think an interval is a term from high school algebra. It would never occur to you to actually write down how far you ran. You don’t receive at least three entry forms a week in the mail. You have no idea how to take your pulse. You think watching other people run is boring. You don’t run in the rain. You’ve never heard of Jim Fixx. You’ve never heard of Bill Rodgers. You’ve only seen "Chariots of Fire" once. You wouldn’t dream of eating anything called "Gu". You haven't been on a high school track since, well, high school. Thanks to Michael Brennan for these contributions to resolving the "runner vs jogger" debate!
