When asked how long your training is today you humbly answer: three to four hours.
You consider work or school as regeneration time between training sessions.
That charming "cologne" you wear to work is chlorine.
When a co-worker or friend asks if you are racing this weekend, you say "yeah, but I'm just running a 10k, so nothing too crazy".
Conversations with tri-friends concerning lubes and chafing carries no sexual connotations.
You have no trouble pushing a day's caloric intake to over 6000 calories.
Your living room has a "swim pile" a "bike pile" a "run pile" and a "weight training pile" and you pick and choose kind of like a cafeteria on your way out the door.
You have no FRIGGIN' idea what to do with yourself on your "off" day.
Your friends are insanely jealous of your tan legs. Until they realize that the tan stops at your bike shorts.
You start scheduling your weekly appointments around your training schedule.
You precede all of your non-brick workouts with "just". As in "I'm just doing a 10 mile run today" or "I'm just doing a 60 minute swim".
Anything later than 5:30 a.m. is considered sleeping in.
Your 'check engine' light goes on in your car and you wait months until you get it fixed, but when your bike is a little out of tune it's in the bike shop the next day.
"If God invented marathons to keep people from doing anything more stupid, triathlon must have taken him completely by surprise."
