Sarah, that makes sense to me as well.  I suspect the long hold time 
allowed the suppression of insulin normally occuring during exercise 
to decrease.  The resulting combination:  carbs AND increasing 
insulin AND resumption of blood suga- draining exercise would result 
in low blood sugar while out on the trail or "bonking".  I have 
exercise-induced hypoglycemia and know that after a period of 
shakiness, weakness, inability to concentrate etc I will become 
frantically hungry.  I avoid this by not eating carbs within an hour 
of exercise, however can eat carbs during exercise with no problems 
since insulin is suppressed.
