Talk Test I've already mentioned the different metabolic / energy pathways. It is all really simplified but in basic terms you either burn fat - virtually unlimited - or sugar, which is in limited supply. Sugar needs more oxygen and burns dirty, producing lactic acid. (I know this is all simplified too much). In terms of endurance you need to stay aerobic / fat burning.

You will not be able to go for long, since you will run out of fuel and the muck produced by burning sugar will stop you. Anaerobic - intense intervals etc - are good at making you more efficient and fitter, better at burning fat but they are for tra...
