OMG! I think we have the same frickin coach! I got yelled at by my supposed coach (cock roach) today too!
But I digress...
That doesn't look like much of a taper to me?? I would swim less, bike around an hour with maybe a short- like 15-20 minute transition run, and then maybe 1 more short run, and thats it. Maybe another day with no more than an hour in the saddle.

Ok, so back to the coach thing. PLEEEAAAASSSEEE tell me that you are done with him. He sounds just like mine, and let me tell you, it's not going to get any better.
I didn't even want mine to coach me, I wanted him to coach my husband to his first IM, but he insisted that he wanted to coach both of us. Well this morning was spent with him berating me because he asked me when I was going to start my IM push and I said January. Apparently he thinks I should start now or something. But I know me, and I know my body, and I will get burned out. If I don't take the month of December to enjoy the holidays and chill a bit I get cranky and shut down. It's happened before.
The way I look at it is I stay in good shape all year, and I could go out and ride 50 miles and run 10 off the bike right now. I have a good solid base. I watch people that train the long stuff year round and it's not pretty. Injury, burn out, and a loss of love for the sport are just some of the side effects of that kind of training.
I do Ironman for the love of the sport, not because I'm gunning for a Kona slot. Do I always try to improve and get faster? Yeah, but I'm fine with small gains. I don't have the drive to kill myself. It's not THAT important to me.

And with all that said, I think we both need to find a coach that will help us create solid training plans that keep us happy, healthy, and racing. Not necessarily push us so far thinking with enough training they are going to turn us into elite athletes or something..
Not one who has his own agenda, our personal goals be damned!
