This is me finishing my first triathlon nearly five years ago, the Finger Lakes Triathlon, in September 2005.
I had a blast and after that race, I got hooked by the sport.
Why I still "Tri": To stay healthy, feel good, stay in shape, handle the stress of life, and to set a good example for my patients.
Triathlon is a great sport to get into. If you can swim, bike, and run, you can do a triathlon! Pick a sprint (short) distance race, and start training! Of course, see your doctor first to make sure that you are healthy enough to train.
If you are in Los Angeles, look into joining the LA Tri Club. They have lots of great workouts for beginners all the way to seasoned athletes. And, find a race to set as your goal -- I love the Hansen Dam Triathlon, which is a friendly sprint-distance triathlon in August, and you can read my race report from the 2008 race.
