after 10 years of tracking my "data" with my garmin watch I can say that doctors don't care about the information and the novelty has worn off, just go ride your bike and don't stress over it. it's one more gadget to remember to charge. I like information but it really doesn't matter, when this watch dies I'll buy a nice watch with no regard to wether are not it "tracks" my data. just my opinion. I had a stroke 10 years ago and thought the information would be helpful to me and doctors but they really aren't interested.
