[QUOTE="LittleGreyCat, post: 1709527, member: 6467"] In the summer I regularly cycle around 50k (which is around 30 miles) and usually just have my morning coffee/cream/butter which sees me through. As others have said, if you are adapted to mainly burning fat for energy then you should be able to sustain exercise for longer without "hitting the wall" because there is a limit on how much glucose your body can store, and also a limit on how much it can take in and process over a period of time. A bit like the traditional bath tub arithmetic; you run the taps to fill it and take the plug out to empty it. In the case of glucose the taps can't run fast enough to keep it filled and after a while the bath tub empties. Then you have no energy, legs turn to jelly, mind goes away with the fairies. The wall. I can't find the figures at the moment for the maximum amount of energy the body can store as glucose and fat, but you can carry way more fat around than you can glucose. So if you are adapted to burn fat then (in theory) you have a much larger energy supply available. For this to work properly you do have to be adapted to burning mainly fat. [/QUOTE]
