This weekend I completed the Bike and Run of the Ironman Pocono Mountain 69.1 (since the swim is 1.2, I've removed that from the planned 70.3 distance). Overall it was an amazing experience, and even though the swim cancellation was a HUGE disappointment to me, I'm glad I did it. I thought I was prepared, but actually doing the 56m bike and then the 13.1m run I was able to prove to myself that I really could do it.
I was Paleo except for my the Powerbar Gels and a little corn in all of the days leading up to the race and even on race day. I didn't hit a wall or bonk at all, I felt good nutrition wise throughout the whole race. I probably should have had a little more on my run, and had I done the swim then I'm sure I would have felt the need to "eat" something sooner than mile 16 on the bike. Generally I eat something like a lara bar or a gel as soon as I get on the bike after finishing a swim.
Here is a recount of what my food and nutrition looked like the days before the race and then during the race itself:
Pre Race:
Added some extra sweet potato and some acorn and spaghetti squash (for variety really) to my meals starting on Thursday (race was Sunday).
Dinner night before was grilled chicken, salad, and mashed sweet potatoes, and lunch had been a burger with no bun with pork roll and a fried egg on it (this was delicious btw) and a half a lara bar.
