I don't think you need to practice it 5 times. Once or twice is probably plenty. I practiced the getting wet and getting on the bike transition just once before my first tri, and I was totally fine. I did more bike/run bricks, though, to know that feeling of Jell-o legs.<br><br>
You won't have much room. You might even be set up under your bike, depending on how many people/racks they have. I use a folded up beach towel as my staging area (you need it to dry your feet a bit too). If you have bike shoes, put them closest to you with your socks, sunglasses, and anything else you need on the bike. Then, put your running shoes behind them with your hat, race belt, and whatever else you need for the run. I put my helmet on my aerobars, but you can put it on top of your cycling shoes too. Make sure you have your water bottles on your bike (I drink Gatorade on the bike). Also, have an extra water bottle to use to rinse your feet (sometimes you don't need this, but you never know what you have to run through from the swim)<br><br>
I would also recommend reading this. I got lots of great tips from this article:<br><a href="http://www.trinewbies.com/Article2.asp?ArticleID=38" target="_blank">http://www.trinewbies.com/Article2.asp?ArticleID=38</a><br><br>
Once you do it once or twice, you'll be ready. You just want to practice to make sure you have everything and to work out any glitches. The #1 thing is to know where your bike is when coming in from the swim and the bike, so look at where the entrances and exits are so you don't get turned around. If you can get at the end of a rack, that's even better. I will look at the swim entrance and note if my bike is on the right or left and how many racks over, etc... Then, I'll do the same from the bike entrance (they are often different places, but it depends)<br><br>
Good Luck!
