As far as my level of fitness, I consider myself average. I play soccer once a week, and ride my bike to work. I enjoy rock climbing, paddling, racquetball, and snow skiing when I get the opportunity. I end up working out 2-3 times a week or so. I'm not out of shape. But I'm not a marathon-girl, either: I never go for 50-mile bike rides. My interest in working out is mostly to keep my body fit, and not for the enjoyment of the exercise.
Doing this triathlon is definitely out of my usual scope. I decided to give it a try because I think it is an attainable, though challenging, goal. It will be an interesting project to devote six weeks to my body and see what the results will be, what I'll look like, how I'll feel, and if my attitude toward exercise has changed.
Another consideration is my asthma. It is, fortunately, mild; but, unfortunately, exercise-induced. Before working out, I take 2-3 puffs on my inhaler. Then, I often need more after getting warmed up. It's manageable, though; just something else to be aware of.
