Ironman Training- OY!

[Running Mommy]

I'm in the thick of IM AZ training and I need some helpful advice from any of you Iron vets out there. Or even any of you girls that ride loooonnggg....

First, when you ride over say 60 miles what do you use for nutrition. So far I've tried carbo pro mixed into cytomax. I also discovered pringles in the single serve pack. I put one in my camelback and one in my bento box on my frame. They seem to work well, but I'm also looking for some other ideas. Gel of any sort makes me gag- a texture thing- so I need something non gel that will keep me going. I'm also planning on adding some salt tabs into the mix as well because I tend to lose alot of salt when I sweat and then consequently cramp on the run.

Second, SHORTS! I have a nice pair of PI shorts (sugar I think?) w/ a purplish color chamois that seem to work well, but I need another pair of "long distance" shorts. I was wondering if anyone has tried the Castelli or Sheebeest?

and finally... How do you wrap your mind around the distance? It seems like I get to 50 miles and my mind starts sayin "ok, I'm bored w/ the bike now". I know it's mostly mental because my legs are fine- well not "fine"- but ok and still moving... Let's just say I know my legs have more in them, but my mind seems to shut down.

Training so far has gone pretty well, but I'm just now starting to get into the long distance stuff. I've got a 70-80 mile ride followed by 10-13 mile run brick scheduled for tomorrow. This is going to be my confidence building " I CAN do this, I AM Ironman material" workout- so wish me luck!
Happy training and thanks in advance for any helpful tips you can throw my way!
