Tapering for Austin

Today is Thursday. I race tri rock Austin on Monday.
So I am tapering a bit. Sunday was scheduled rest then this week on my 70.3 plan was a testing week so the vol was lighter anyway.
I have even made it to a couple I Crossfit classes! Tri bodies are pretty unattractive and I can see myself developing one.
Anyway, Saturday and Sunday will be light for my 1/2 iron plan and I will rest Tuesday but then I plan to be backin the swing on Wednesday.
As for Austin, I really don't know what to expect. If the course measures the same as the earlier oly, I can see getting into the 2:30's. I think I am running smarter, swimming better and transitioning quicker.
BUT the course measurement might not be the same.
So, here is what I can control:
I want to get a practice swim in. It can be the day before. Fine. I just want to have been in that water. I think it will calm me down. Ideally, I just want to swim steady the whole way. If the course is long, fine. If I have to go wide, fine. I just want to swim straight through.
The bike seems like a straighter course than captex. But with a little more hill.
I really don't know what to expect. I am worried that I will not bring enough intensity.
On the run, I want to go by heart rate and cap myself at 160 for the first 4.2mi.
Last time in Austin, I had to walk a few times. I would like to avoid that this time.
