Geranium, I don't know if you're looking for a local olympic or you are planning to travel, but there is an oly here in Indianapolis on August 1 (I'm doing the sprint that's at the same time). Good luck on the marathon!
Muse, I'm surprised there aren't more people here too! Maybe people just don't look at the Exercise forum that much. I will go promote our thread on the maintainers forum, I know there are a couple triathletes or aspiring triathletes there. I tried on the tri top over my sports bra yesterday and it felt okay, although I didn't do anything active in it. I'll try the combination next time I go for a run or a ride and it's warm enough to not need long sleeves. Good luck with your HIM!!!
Au, good luck!!! Definitely come back and give us a race report after your sprint. How much did you spend on your bike? I'm vaguely considering getting a road bike to replace my hybrid but I am cheap.
Eliana,

! The one sprint I did that had a swim in the pool did not require flip turns (although you were allowed to if you wanted to). The standard triathlon format is that you put your bike, shoes, etc. in a "transition area" before the race starts. Then you start the race with the swim, get out of the pool/lake/whatever and run to the transition area. In the transition area you do whatever clothing change you need, put on your helmet, and get your bike. You run with your bike to the end of the transition area, then get on the bike and ride off on the bike course. After the bike, you end up back at the transition area, where you put your bike in a rack and take off running. So they are all one right after the other.
In any case there are people of all abilities in triathlons. You can look around and you might find one in your area that is specifically labeled as being good for beginners. The first one I did was a beginner's triathlon and had people doing breaststroke, backstroke, and even dog paddling their way through the swim! I would suggest trying to learn to breathe on both sides. I breathed only to the left last year until I took an adult swim class this winter, and since I learned to breathe on both sides I've been much faster. It is really hard at first but the more you do it the easier it gets, and now I feel weird if I only breathe on one side.

Tea! I'm a back of the packer too -- well, back of the back of the pack. I'm hoping to just be back of the pack this year instead of, you know, dead last.
So I was planning to do two tris this season, one on July 17 and one on August 1. But now I'm wondering if they will be too close together, and if I should do one in June and the one in August. The August one is for sure since it's the same one I did last year and I want to improve my time. If I sign up for the June one it is coming really soon, but I think I would be okay. On the other hand, I have more time to prepare for the July one, and two weeks between races should be little enough that I stay in shape while still being long enough to recover a little. What do you guys think?
Also, how do I know if I need a wetsuit? The June/July tri has an open water swim in a reservoir. I've swam in that reservoir with just a swimsuit in summer before with no problem, but I didn't go very far from shore.
