Am I missing anything for my 1st TRI???

I recommend sunglasses just for flying bugs Also, another (cheap) investment could be a race belt. Are you using clipless pedals? Don't forget your bike shoes!

Good luck at your first race & have a great time!!! 

I don't wear sunglasses because I don't have the kind you can wear while biking or running, but they would be a nice extra.

I bring an extra small towel and bottle of water to rinse my feet off after the swim - I think it helps a ton.

I also bring M&M's to eat at T2 - I think they help a ton too.

I almost forgot to say Good Luck!!!

Sunglasses (as much to keep bugs out of your eyes as anything)

Sunscreen & Lip balm (skip the bug spray)

Tire pump or inflator that you can take on the bike with you.  (Won't do you much good to have a patch kit if you can't refill the tire.) 

Nutrition (for before and after the race, you may not want their post-race food) and a quart of drinking water (so you aren't at the mercy of the race for post-race hydration).  You might bring Tylenol or Advil and stuff to treat blisters (you'll be in a hurry pulling on socks and shoes which can lead to blisters even though you don't get them training).  (Do you need coffee/caffeine?) 

Change of clothes, maybe enough extra stuff to do a nice clean-up until you can get a shower. 

Water and a towel to wipe your feet and a second towel to stand on (these can both be pretty small)

C A M E R A !!  You'll want pics of this first race (and we'll want to see them)!! 

Support crew/Adoring fans? 

The only thing I can add is don't forfget to RELAX nothing will mess you up more in the transistions than being to keyed up trying to move fast etc you will forget somehting in transition or fumble around etc. this is your first race take it easy slow down a bit get the feel of how it goes what the flow is like etc. you will enjoy it more. The adrenaline can be tought to control. Have a blast.

Have you practiced this as part of your transitions? I know, broken record, but it's not easy to put clothes on when you're wet.

Also, have you practiced riding/running with two sets of clothes?

You definitely want to practice this transition.  I did that for my first tri and it was really hard to get on clothes after I was all wet. 

I would second or third the idea not to put on clothes in T1. Only exception is if it is really cold and you use a jacket.

I made my kids practice transitions and I would recommend you try the same...I'm not kidding either.

Set up your T1 area in your driveway. Get in what you plan on swimming in, get totally wet. Now run around a tree 5-10 times so you are nice in dizzy which is very typical getting out of a swim and standing up to run to T1, then transition, get on your bike and ride 5-10 minutes; now come back and do it again and again until you feel you have the timing/order of what you'll do down and where you'll put stuff.

I would also suggest getting a number belt. I put mine on before the start of the tri, roll it up and put it on so the number is rolled up behind me then when I come out of T2 I can unroll it and spin it around..saves time. 

I'm a quick T1 & T2 person....I set up my bike shoes open, sunglasses in my helmet, helmet so when I lift up my helment goes on my head the right way...run to transition area, put on shoes standing up while same time sunglasses and helmet and off I go.

Behind my bike T1 stuff is my T2 stuff shoes unlaced with a sock in each, and if I'm bringing drink with me my fuel belt or hand held drink holder.  

Other keys is to really get a picture of where your T spot is so you can find it..practice coming into T and finding your spot..count trees, fence posts or whatever to help guide you.

Doing smooth transitions helps lower your time, plus no need to get flustered in this time period. I often place higher as I beat folks in transitions.

Not sure what time sunrises in TX, but if it is dark when you set up transition it can be challenging..so I bring a headlamp or simple is a flashlight. 

 Bring the camera, a good attitude and soak up the fun of your first tri as it is a great new experience.

Sorry (I haven't followed all the threads)...Doesn't have to be hubby.  Best friend?  Mother? 

C'mon BT peeps!  we need a Houston posse! 

Sounds dumb, but it is 100% true!  Anytime I get a new tri suit I hose myself down and then go for a ride at least once a wear it in a race.  Doing that I've learned that I dont like racing DeSota tri shorts, because they ride up when wet.

I also second the idea of physically setting up your transition and running through it multiple times before race day.  You'll figure out what you need/don't need by doing that.  Everyone's got a different routine, so figure out what works for you!

I'll be racing CB&I too, so if you've need any more help...just ask!

I third or fourth the idea of not pulling clothes on in T1. My first tri I tried to pull a tank top over my swimsuit and it took forever - kept bunching up and stuff. If nothing else, go to Target or Wal-Mart or wherever and get you a fitted tank (preferably wicking, not cotton) and wear it for the swim. I did that for my last tri last year, and it worked pretty well. And don't worry about the shorts over your bike shorts unless you really feel the need to wear them...

Have fun!
