I guess in the flat terrain of much of Florida you have to do something to amuse yourself on the bike. But for me and probably many, sprints aren't our thing. We'd rather best our times going up a hill or see how fast we can average on a 36 or 62 mile ride or some ride of more than two hours.
I tend to think the benefit for health is duration of ones cycling as opposed to short bursts of maximum power. Though when used for interval training those short bursts of maximum effort can improve everything else.
I suppose when I started back riding my 46 pound Schwinn Varsity for fitness back when I was about 50 yo I had some of the same feelings of how "great" I was and ready to challenge all comers. However I think I'm a little more sensible now on my <18 lb bike and a little less likely to challenge anyone lest they embarrass me. < big grin>
