I went for a ride today having had a bowl of all-bran with sultanas for breakfast. I was pretty much powering up the first 9 or 10 miles which is almost all uphill, and the worst of the hills on the ride at that. But then the next 6 or 7 miles, which is fairly undulating, but i would say the ups aren't quite as bad as the beasts of the first bit, i was hitting a wall at about 13mph even on the flat at the top of the hill. I'm sure it wasn't the bonk because the only tiredness I felt was you know when your quad muscles feel like concrete, like that. I was impressed with myself on the first bit out of town, but then through the villages while I didn't embarrass myself i thought I could have gone quicker if i'd managed my energy intake/usage better. So I was just wondering, how much energy does all bran actually give you? I know it's mainly fibre, but does that actually contain any energy? Would I have been better to have eaten something involving some pasta, say? And what about bread? How much energy does, say, 2 slices of thick-sliced wholemeal loaf contain, compared to say, an average dinner-time helping of a pasta-rich meal?
