Hmm.. I didn't get that email. Maybe it's because I did it last year.
No need to be scare. It's a very newbie-friendly race. No mass start of the swim (line up by and jump in pool one-by-one, every 20 seconds), so you don't feel the pressure of someone faster than/catching up with you. You're racing against yourself. No fighting through a crowded transition area - everyone started at a different time.
The down side of this race is that it took so long to wait for your start.
I think DK is right -- no need to worry. Several friends at my gym ran it as their first tri last spring and are going back to do it again this year. They had a blast, so I'm joining them. Maybe see you there!
