Hi Nanci,
Well, I am doing my first tri ever in 2 weeks. It's the Danskin tri in NJ and I am also scared of the swim. I have problem with freestyle as well. I am planning on swimming breaststroke all the distance. Let's hope i don't drown. And I also just learned how to ride a bike 2 months ago. So, I am excited and scared at the same time.
I hope your race goes well and you have fun!
