Pretty much every triathlete has a reason they tri. Some people were challenged by a friend and got hooked, while others did it to test their body's physical and mental limits. But most everyone who CONTINUES to tri, does it to maintain a healthy lifestyle. I know I do. And as a perfect example, I had this conversation with my doctor yesterday when I went in for a physical:
Dr: How often do you exercise?
Me: I pretty much do something 5-7 days a week, depending on my training schedule.
Dr: Oh, what are you training for?
Me: Well, I've been competing in triathlons for the past 3 years.
Dr: That's great, I'm really happy to hear that.
After checking vitals...
Dr: Well, you are probably the healthiest person I've seen in my office in a long time.
Dr: In fact, you just made my day.
A doctor sees hundreds of patients a week. So for me, those were all the encouraging words I needed to hear...
