First of all, relax and just let it be a fun learning experience. Just finishing the first one is a huge accomplishment. Don't get hung up on your time or where you finish.

Second, try not to max yourself out in any one part of the race, except maybe the end of the run. If you burn out on the swim or the bike you won't be there for the run. But if you leave something in reserve you will be able to do the whole thing.

If the bike is your weak part, definitely work on that the most in the next few weeks. Try a few bike-to-run transitions/ bricks just to get your legs used to it. You don't have to go far in the run. Just a few minutes will give you an idea of how it feels. I wouldn't do this every time, just once or twice a week.

Pack your stuff the night before. If you try to do it in the morning you're guaranteed to forget something. Here's a web site for a good check list for race day: http://www.coremultisport.com/Docume...yChecklist.pdf

Give yourself some rest time the week before the event. Don't overtrain. You want to go into it rested, not tired.

Last HAVE FUN! The first one is nervewracking but such an accomplishment.
