I am also throwing myself into the ring as a late blooming discover-my-inner-athlete tri girl! I am having to learn two of the three disciplines (running and swimming) and will be doing my first mini sprint on May 11. It is a 400m pool swim, which is a good thing because I am still having to catch my breath after 25m! The run is 2.3 miles, which I am almost up to doing now, and the bike will be an easy (for one who is not actually racing) 7 miles.

I have also signed up for an open water sprint tri in July and hopefully will be ready to swim without stopping by then.

Lots of great info on this forum. I discovered Total Immersion and Chi Running here and I think they are key to my being able to do this new endeavor, hopefully without injury. I am loving training in three disciplines, especially in the winter (it's still winter here) because there is alway something I can do besides grinding away on the trainer!
