Nutrition on the road - What, How and Why?

His bacon and egg rice bars are amazing. Very delicious and apparently really good nutrition. You can find the recipe with some googling. I made them last year much to the joy of people I rode with. A friend used them on his ironman recently and thought they were the dogs bollocks etc.

Bacon and egg during a race? Sounds like failure to understand nutritional requirements for endurance exercise. I hope it was a tiny amount for flavouring?
