My too. I used to be a competitive runner but the longer the race, the better I did in comparison. I used to go through the 10K splits ina ten mile race or half marathon in close to my 10K race time.

I also played sports in high school and college - baseball was my best, I got killed in football with my weight (didn't attempt that in college), and basketball but gravitated towards the slow twitch things when I got older - running, cycling, swimming, etc.

I'm also a sailor and love the competitive aspects of racing too. This winter my wife and I went on a cruise and got to race on American Cup boats on an excursion - one of the most exciting things I ever did.
