RE: carb intake on longer runs.
I've run up to two hours now, right after eating breakfast consisting of 2 eggs, cheese, and a slice of ham or pork cutlet. I felt fine, having at least a 1/2 hour before running. I was a bit worried at first, but did not experience any discomfort, nor lack of energy. In fact, I felt I could have carried on. I breakfasted at 05:30, and was feeling REALLY hungry by 10:00. Other than that, no problems/concerns.
p.s. Quick, easy, delicious breakfast?
Small frying pan, heat on medium.
small pat of butter, break in two eggs
let them set a bit, put on some luncheon meat, sliced ham, whatever you have handy.
Top off with some TASTY cheese ( my preference - Monterey Jack with Jalapeno, or OLD cheddar )
Place a lid on top, and let it set for about 2 or 3 minutes.
When ready, remove lid, and slide it onto a plate, season as desired.
Yum, yum, yum.
