[QUOTE="tim2000s, post: 1230720, member: 30007"] It's physiologically more complex than that Julian. Exercise increase the action of Glut4 Receptors within the muscles, so if your blood glucose level is in the normal range, your muscles can use glucose, and often your basal insulin will be enough of a catalyst for this to work. This is why, when exercising 3 to 4 hours after eating, we are advised, if it is aerobic exercise, to eat carbs. Anaerobic exercise is a different kettle of fish, and usually causes a liver dump that drives up blood glucose levels, in spite of Glut4 activation. My experience of cycling without taking fast acting or breakfast is that I was fine, but I was travelling 13-14km rather than 30. I think I'd stop and test every 15 minutes if it was my first time doing it without breakfast, especially as you don't seem to notice going low when exercising. [/QUOTE]
