How did this start?

I have this awesome niece who recently graduated from medical school and has a very inspiring blog (you should check it out). Well . . . she trained for and entered the Tri Indy triathlon last summer and did very well. So, I thought - "hey, maybe I could do that". I'm in reasonably good condition - for my age. Back in the day I was a pretty fair swimmer - and most folks find that to be the most difficult stage of the triathlon. I can run 5k pretty easily and, riding a bike should be - well, you know . . .
So, the next thing I know I've signed up for my first event. Okay, I just signed up for the "sprint" distance (roughly half the Olympic distance) but that seemed like a prudent move 'cause I'd hate to pop a valve in my first race. That would sort of defeat the purpose of wanting to get fit so I can be around to meet my grandkids!
So that's how it started.
I hope I don't hurt myself.
