1. As soon as you get to your feet then unzip and take it down to your waist. Cap and goggles off. Then run to transition to final strip off. Having body glide on your lower legs seems to aid with getting it off your legs.

2. It is faster having the shoes on the bike and going sockless. However this takes quite a bit of practice.

3. Over the last part of the course prior to the dismount line pull your feet out of the shoes and pedal with feet on top of shoes. Then as reach dismount line swing leg over and hit the ground running. Again practice practice.

4. spare tube, CO2, adaptor, tire tools

1. Like RV says. As soon as you stand up, unzip and take the top of your suit off down to your hips. RUN to your spot in t1. Drop the cap and goggles. Grab the waist of your wetsuit and scrunch it down to the ground (so you have the legs on about half way with the other half folded on top). Then one leg at a time, fold it down again and then hold down what's left around your ankle firmly with both hands and pull your foot out of it. Bodyglide on your lower legs helps.

2. 1st put on your helmet. The fastest way to do it is to have your shoes attached to the pedals. You RUN to the mount line and jump on and then get your shoes on. I would strongly advise against this if you have not practiced a lot. I've seen plenty of riders messing this up and swerving. Its a pretty small saving over just putting your shoes on in t1 and then mounting by stepping on one pedal and swinging your other leg over the bike.

3. The fastest way is to unvelcro your shoes and slip them off. Pedal on top of them for the last fifty meters or so. Then slow down to an acceptable pace and swing one leg over the back of your bike. Bring your leg in between your other one and the bike and hit the ground running and keep running until your t2 spot. Rack your bike handlebars in this time and then slip on the shoes, grab the number and go. This is much easier to learn than the t1 tricks and its a bigger time saving. Its worth taking the time to practice this. Make sure you know what an acceptable speed to come off the bike at is because if you are going too fast, then you'll eat it.

Transitions are fun! I love passing loads of people in transition and I think that its my favorite part of the race. Its free time! They are always the strongest part of my race.

4.
I generally don't carry anything for race. BUT, I race frequently and I only do sprints and olys, so one bad race won't really get me down. AND I am usually racing for an overall female podium spot. AND I race on tubular tires so if I do happen to flat, I ride them in (I've seen this done on clinchers too, but that is much slower and more dangerous). I've done almost 30 triathlons in the past 5 years and I've only flatted once in a race 10 miles into an oly. I just kept on biking and still averaged 18 mph or so.

There are plenty of people that will argue for always carrying flat protection. So, if you are carrying stuff, the essentials are: patch kit, tire lever, co2, adaptor, 5mm allen. A spare tube will make a flat repair faster, but its also much bigger and heavier. I have had a waterbottle cage and my aerobars vibrate loose in races before, hence the 5mm rec, but those were lessons learned to give my bike a once over before each race.

Good luck!

1. body glide is your friend in this case! What we do is like other have said is to get unzipper and hopefully you can pull it down to your knees then just step on it and pull the other leg out then repeat (be carefull though pretty easy to tear a wetsuit this way buts it dang fast!). One other quick note to make getting the suit on (besides body glide) but your feet in plastic grocery bags and step into the suit with those on then just take them off when your feet are through.

2. I'm personally slower with my pedals on my bike as I have to stop pedaling to get my feet in so I just strap them on in T1 and run with them, not too bad usuall. Oh and catwood had it dead on helmet is the very first thing, in many tris you touch the bike without a helmet and its a your DQd.

3. I would say that you should get out of your shoes and just stand on them for your last 1/2 mile but only if you have tri shoes, otherwise its a big hassel and will just slow you down.

4. Depends on the race and your goals. When I think have a podium chance (insert laughter here) I wont carry anything buts usually only for sprints. In olys I carry 1 CO2 cartridge, inflater head, tire lever,and a spare tube anything more then that imo means your doing too much maintance on the course and on course maintance is usually rough at best lol

First of all, if you're riding clinchers NEVER DO THIS. The bead will roll and the metal on the rim will touch the road and slide right out from under you. If you're on tubulars and really want to do it, go really easy around the turns and don't brake on the wheel that has the flat.

well, can't do that then...
thanks for the answer!
