Topic: Cramps & Exhaustion out of nowhere, WTF?

[Daniel]

Oh, and you are right. Cramps will come for one and all. The body is like any machine. The only question is which part fails first. Because I am out of shape it's my respiratory system that fails long before I get cramps. For others maybe it's cardio-vascular. When you are in shape you can push those systems until your body begins to run out of the fuel and chemicals it needs to operate and the muscles stop you if you don't stop them first. What seperates you from Alan is that his onset was premature for a guy in good shape. Your experience is just a boundry that you are training past. Nutrition at it's extreme is akin to those fancy refueling canisters that they use in auto racing. How fast and efficient can you get the stuff where it needs to be to keep going without stopping too long.
