An important point to remember is that in large part, carb consumption is determined per day, so that
on days you train hard, you'll be consuming much more
carbohydrates than
on days you train
light or don't train.
A couple of observations: Based
on your recommended level of
carbohydrate intake I'd probably be reduced to
light jogging within 60 minutes, and
on a day where I burn say 4000 - 5000 calories, easy when its cold, I would require ~ 300g of protein?
