I'm six weeks away from my third Ironman Canada and this year I'm feeling great, much better than last year and I'm in a much stronger and better mental state than in my first year. The next three weeks is the final push of training which will include a triple brick workout (a 2 hour bike ride, 1 hour run 3 times through) and then the Marin Century ride the week after.
This year, if I run I should be able to shave off at least an hour or so off my total time from last year. I'm looking at staying within the 14 hour range this year, if all goes well. It should, I'm in better shape, healthy, and I'm in a much better groove w/ my nutrition.
I'm on a strict six week diet which is oatmeal for breakfast in the morning, all the fruits and vegetables I can eat, chicken breasts, eggs, lean deli meats, fish, and tofu. No bread, no cheese, no sugar, no coffee. I'll get all my carbs mostly from the training ride food I use. I'm still hovering at about 180-185lb but I'm in the 8-10% body fat range (versus 12-15% from a couple months ago) so something is going right. I should drop to at least 175lbs when the six weeks is up.
