Nutrition Calculator

This seems like a good resource but now I have a couple questions.  the calculator suggests that I consume, roughly, 400 calories per hour. 

I suspect that SCHIM will take me almost 7 hours, so 400 cal/hour is about 2800 calories.  My current nutrition plan, that I've practiced on the bike, has me at 2660 by the end of the race.

My questions are related to timing.  I should be dividing those calories up differently between the bike and run, correct?  And, does this total include pre-race calories? 

My nutrition plan:  Pre-Race = 770 cal; Bike = 1350 cal; Run = 540 cal for a total of 2660 calories.  By the way, those pre-race calories are consumed gradually over about 3 hours prior to the start.

Input would help as I only have two more good opportunities to practice my nutrition.  This weekend I'm doing a long brick and later in the month I'm hoping to do a century ride.  

I assumed my breakfast didn't count towards my race nutrition, but anything I consumed right before the race would.  For example,  I plan on taking in two gels and sports drink right before the start.  Those 250 cal are part of my plan.  I used the calculator to double check that my plan was in the ballpark of what was needed.  Everyone is different. 

If you try to down 400 per hour, you better try it before the race.  Also, getting 540 cal while running is a real challenge.   I found you have to / must try different levels.  It is a very frustrating topic because it is very different for each person.  Last year, I used an OLY to dial in mine before my first HIM.  During workouts, I figured out that bananas make me yak  on runs over 10 miles.  Go figure. 

Tri talk information will put you in the ball park, then play with it.  Also, try different types of carbs.  If you listen to the tri talk pod cast, it is critical to get different types of carbs.  Check out the labels and try to mix it up some and not just get simple sugars, etc.

Yikes! If you try to down that many calories you are just asking for GI shut down. For the bike ~350 cal/hr (and that is on the high side) for the run you are going to be lucky if you get more than ~150 cal/hr down. Remember it is impossible to replace calories at a 1:1 ratio...it just can't be done. That is why we train at low intesities to train our bodies to burn from our fat stores.

Good luck.
