If any of the following are true for you, then you might be a triathlete--indeed, you might be taking this triathlete thing a little bit too far.
1. If you have magic marker on your skin underneath your business attire, then you might be a triathlete. They are either left over race numbers that haven't yet worn off, or you are a toddler and your parents need to do some childproofing.
2. If your business colleagues ask if you "still ride your bike," and you just smile and say yes rather than explain the hours of swimming and running on top of the whole "ride your bike" jaunt that your colleagues imagine, then you might be a triathlete.
3. If your mother-in-law, the Avon lady, gives you "Ironman" aftershave and cologne, then you might be a triathlete.
Thankfully, it does not actually smell like Ironman. I guess urine and B/O did not sell.
4. If you have to take a bike trainer, a wetsuit, a bike, four sets of workout clothes, a helmet, bike shoes, sunscreen and nutrition on a two day business trip, you might be a triathlete.
5. If you doubt whether a session adds to your fitness in the absence of Garmin data to upload to Training Peaks and share with your coach you might be a triathlete. For that matter, if you are over 40 and you have a coach at all, you might be a triathlete.
6. If you associate a massage with pain, you might be a triathlete.
7. If the word "base" does not conjure images of the National Passtime and "taper" makes you think of racing rather than candles or shapes, you might be a triathlete.
8. If you cannot stay awake in a darkened movie theater for two hours, you might be . . . a . . . z-z-z-z-z-z *snort*
9. If you start thinking on Monday about where you're going to ride on Saturday and who with, you might be a triathlete.
10. If you think neoprene is hawt, you might be a triathlete.
