My goal for this tri is just to get through it and learn the drill. There are so many basic things about a tri that I am not familiar with because I have never done it that doing it without feeling a big pressure to go fast may be a good thing.
So, as long as you won't be in danger during the swim, then go for it!
I'd rather be swimming...biking...running...and eating cheesecake...
