What to eat the week before Olympic triathlon

x2.  Except I might not be so good at cutting back on the bad stuff.

You should eat as you normally do (assuming you eat nutritiously and not garbage).

Carbo loading takes place over the week or so before the race and has to be incorporated with a proper taper and reduction in training to really work correctly.

There is a way to supercompensate your glycogen stores by going out on the bike, warming up for 15 minutes or so and then doing some super high intensity sprints for around a minute or so with a few minutes recovery between each and then eating a larger high carbo meal afterwards as your body tries to supercompensate thinking that it is going to be depleted more based on the anaerobic efforts.  But this has to be done properly or you will not build up your stores correctly.  It is a risky approach.

But the reality is, you will always have enough glycogen stored for about 2 hours of excercise using strictly glycogen for fuel.  As long as you are eating a normal diet during the week and not cutting back on your portions for some reason, you will go into the race fine.  Then during the race use whatever nutrition plan you have been training with and you will be fine.
