Triathlon - first tri/transition setup help?

I'm doing my first tri in a week and was wondering how te transitions are setup, what I can/should have there? any help is appriciated

Also it's the tri for fun at ranco seco park in sacramento.

Ah, TBF's Tri for Fun Series. What a blast. I'm doing one of them that weekend. Can't decide if I want to do the Sprint or the Oly.

Anyways. There are lots of sites and books that help you with what to bring. Outside of the obvious (you, bike, etc) the way I set up my towel is this:

large towel folded in half (so its long)

Helmet on top of cycling shoes (if hill at start) at the bottom of the towel

Running shoes with socks 'rolled' in each one, number belt on top of them. If you used a hat, it would go there on top of or under all of it. this is in the middle of the towel

top of the towel is my area to toss the wet suit. I usually get an end slot to put my bag off to the side.

Bring a pump, check your tires at the car and leave it there. obviously a spares kit, some fuel, bike, etc.

Try to be a minimalist. less junk to go through and help keep your T1 and T2 short.

another thing many people do wrong that and should remember:

if you are going to wear a top that you don't already have on during the swim, you should make sure that it's one with a long zipper. cause throwing on a dry top when you're wet can be a real pain...
if you should not have a top with a long zipper at least get the top you do have wet: pulling a wet top over your head is way easier...

or just go the easy way and wear a tri-suit all the time or your top all the way through..

I think its good practice to set up your gear as you are planning to in the race, and rehearse your transitions a couple of times. Not for speed so much as to make sure that you like where your shoes are, what you're going to do in what order, etc. You'll be able to identify things you perhaps need/don't need, and come race day you'll be more relaxed knowing you've got your transition plan all copacetic.

Unless you think you are really coming close to winning, and a slow transition would make you lose, I think you can relax quite a bit and just get dressed quickly. I even dry my feet a bit before the socks (gasp).
Other notes:
You cant put a pullover shirt on if your helmet is already on.
You can't put shorts on over shoes either.

I had my first one Sunday. Was a little intimidating getting your space set up. I forgot a 2nd towel to lay everything on and used a folded tee shirt. I felt dumb but no one even noticed. Also pay attention on how the bike mounts on the rack. when I came into T2 I keep trying to hook the back of my bike seat on rack when it was meant to hook on front of seat. I am sure there are different racks so just note how to do it at the beginning of the race.

Good advise offered above.
As lemurhouse noted, a practice run can be of great value. So can not being in too much of a hurry (Enthalpic).
I'll add that gathering everything togother the day before the race is much easier than on the day of (sounds pretty obvious, but a training partner of mine waits until the morning of and ALWAYS forgets something).
Also, make a list of everything you take. Makes it much easier to prepare for the next
race (add things you forgot, eliminate useless crap etc.).
I have mine finalized and laminated for future use.
Have a good race, have fun, and keep us posted.

Thanks for all the help guys
