Susan,
I will ask my coach about any published materials. He is in Europe this week but when he returns next week. He's actually a very well respected coach and was USAT coach of the year in 2010 as well as coaching some elite athletes. I am lucky that he is also the fitness director at my gym and coaches some middle of the pack AGers like myself.

Like Colby said I am not trying to win, place or even Kona qualify I am actually just trying to finish the race in under 15 hours.

I think that different coaches have different perspectives on the training and the goals as well. I actually don't do LSD runs, as slow as some others recommend. I had asked him about that because I had read that you should do your LSD runs at 1:20-2 slower than marathon pace, and I do mine about 45-60 secs slower than my marathon pace. He had said that since I am more of an endurance runner than a sprinter that my gap between a 5K and Marathon Pace is smaller than average that I shouldn't slow down my long runs that much.

It does seem like there might be a slight mismatch with your coach. Perhaps she's not training you to walk a marathon but she is training you to finish an IM - totally different in my mind. My coach actually said (and I am not sure if I believe it) that is actually easier to run the marathon at the IM then just a marathon because you are not running as fast. I couldn't walk for a week after my first and only marathon so far.

I am terrified about the swim, both the mass start and the fact that I have to swim 2.4 miles

Its great that you are getting the practice with the OWS. I have not been out in the OW as much as I would like so far this season but plan at least once a week between now and the race.

Good luck with your HIM this weekend.
Sharon
