If you're a triathlete, you're intrinsically competative and put a lot of time, energy and resources into your sport. So why shouldn't you dwell on it a bit (okay, a lot)!
The idea behind MyOwnSportSite is to allow you to archive all your records, memories, thoughts and whatever else you want, in one place. Then, from time to time, you can add to your site all that you've done since your last update.
With all your sport information on your own website, not only can you access it anywhere or anytime but also share it with your family, friends, fellow athletes, and potential clients and sponsors.
