So ZUlu, do you think the lower rate for fat burning approach really makes a difference? WOuld it allow one to avoid bonking if you keep the heart rate low? IOW< say you rode without eating much, if you are fat burningm, couldn't you theoretically ride a LONG ways before your fat was converted, as opposed to your glycogen stores?

Also, if you (me) were trying to loose weight, would you be very careful to stay in the fat burning zone?

And finally (and I really apprecaite it if you have actualy been willing to respond to these), how likely is it that smone's HR is not accurately calculated based on the standard fomrula? IOW, can I rely on that? It seems to fit my observed perfromance, but if it is off by 10% that would screw up all the other assumptions about HR range.
