I didnt know that I would be in the last wave out and realized that I ate my breakfast to early as my stomach was growling just before the swim. I also forgot to eat my powerbar before I came down to the beach from the transition area.

Here was my first big mistake/learning experience. I was too excited when the horn blew and completely forgot about form at first. for the first 150 yards I worked to hard, even though I swam slow and was too tired to spot so I went 40 degrees off course from the bouy. At this point I finially calmed down, concetrated on my form, caught my breath and started sighting the bouy. Seeing that i was way off course and 75 yards to the right of the group, I stayed calm and swam/sighted perfect from there to the turn around. At the turn around, I noticed that I rounded the bouy with they guy that was next to me at the start and was about in the middle of the pack. From the turn around bouy to the final beach bouy I swam fast and straight and made up a lot of lost time passing many swimmers.
Then, I made my bigest mistake. I stood up way to early in waist deep water and ran in for 30 yards. This was the worst thing I could do. Not only was it slower, but it required a huge amount of energy and really tired out my legs.

Eat properly.

Stay calm at the start. Swim focusing on form and sighting properly.
Swim up to the beach until my hand touches the bottom and maybe even learn that "dolphin diving" technique to maintain speed and conserve energy.

4 minutes is embarrassing. My Olympic race last year had a 2 minute T1 time.
I think the extra time came from being exausted from running in waist deep water.

2 things slowed me down a bit here. The first was my tired legs from the run through the water. The second is that my legs never really warm up until about 8 miles into a ride. My average was in the low 18's on the way out and I pushed it up to about 20 by the time I got back. If I was doing the Olympic, I would have had a faster time because I would have had more miles to ride after my legs had warmed up.
Is there any way to teach my legs to warm up faster? Just ride more?

Not much.

Last year I had to pin on my # to my shirt for the run. This year I had is pinned to a second shirt, removed my bike shirt and put on the #ed shirt. Problem is the pins pulled through the paper while I was putting the shirt on. LOL Guess it is time to get one of those elastic waste bands that the race # attaches to.

This was just the best I was able to do. My body felt fine, but my lungs just could not give any more oxygen. In fact, I was seeing in tunnel vision during the run as I suspect my head was not getting enough oxygen.

Do more brick training to get used to running after biking.

Mistakes and tight lungs from asthma the night before.
