What I learned from my first HIM (Page 4)

I would recommend you apply sunscreen at T1 and T2. I did a HIM in January (Key West so much easier to get burned) and I ended up with sunburn where I couldn't reach (back area exposed with TRI suit) and the part I forgot (back of legs.) The other areas got sun but no burn.

Different issue though is that I learned that nutrition/electrolyte replacement) on the bike is very important, especially for a hot race. I didn't take in enough calories or electrolytes and ended up not only hitting the wall on the run, but also having terrible lower leg and foot cramps on the run.

I also learned that I probably don't have a IM in me like I thought I might before the HIM

Yes, because something is written down it must be true, and so we must call all workout combinations Brick per the definition.  I stand incredibly corrected and now I will call all such workouts brick.  Baloney.  Once the physiological change is made to the run, the effect of the bike/run brick switches to a run workout on with potentially tired muscles.   Not much different than doing a bike in the morning, and run several hours later.  I'm fine if you go into denial about that, because its still good training.

As I'm trying to help you. There is a lot of energy & enthusiasm, very much willing to help out which is great. But then the post in question could have been stated differently, such as saying that the additional running continues adding on to the brick, but doesn't add to the quality of the brick. It's simply more running. Then you're setting up for a potential discussion instead of either a confrontation or being completely ignored.

And so you know, a number of rather knowledgeable folks will also use the term "transition run". The difference between a brick and the transition run being intensity, with the brick being hard. I don't really have a preference to the terminology so long as the idea is conveyed. That is, the intent of the workout and how to do it.
