I tend to resist gadgetry (I was trying to find my "Running free" post, but the blog search feature doesn't seem to work well), not because I don't like technology (I do) or because I am cheap (just a little). It's mostly because I find it distracting and also think that you can have too much information.
When I was at Dr. Pushy's office the second time and mentioned running, she asked how far I went. I told her I just track my time, not distance. She said I should get this new gadget for my iPod that tracks distance. "It's only about $30." I don't care how much it costs, I don't want to know my pace on a daily basis because I know myself and know that if my pace was slow on a given day, I'd be upset about it. If every workout became a race, I'd find training a lot less enjoyable. I didn't bother to mention that to Dr. Pushy because it was pretty clear that she is not that interested in me or my problems. As soon as I resolve a Coordination of Benefits issue with my insurance companies (the one that is supposed to be my primary is trying to get my secondary insurance to pay for all these tests that she ordered), I'm finding a new doctor.
I have used a heart rate monitor before and I know that they can be both useful and distracting. The battery died in my last one, and it's expensive and difficult to get them replaced. I decided to get a newer one with a calorie counter, as Jillian recommends. My old one just had a heart rate monitor and a stopwatch. This one also has a feature to eliminate interference from other people's monitors, which should be useful in Spinning classes, where I had problems with the old one sometimes.
The problems I had at my half marathon make me wonder if I have been training too hard or the wrong way. I think that having some data could help me make that determination.
