I normally do all my training just after waking up in the morning prior to eating/drinking anything (except water). As I was riding along this morning I started to wonder if by not eating prior to my workout, was I using up more fat to fuel my ride (as opposed to burning carbs that may normally be available if I had eaten). Could this theory be true, or am I just hallucinating due to not eating? And if it is correct, wouldnt it make sense that by "stressing" my body in such a fashion, I would gain an additional edge during a competition by eating (and thus allowing my body, which is used to not eating and having to convert fat into energy, instant "carb" energy)?
I would be interested to hear if anyone has any thoughts on this.
