Running very early in the morning, before taking in any foods forces the body into a catabolic state - eating itself.

This means at the start of training when a fighter may have a few extra pounds it is an excellent method of cutting fat.
Nearer to the fight these long early runs will be dropped in favour of short-fast carb fuelled runs.

Well, I dont see why you can't just wake up at normal time and do your running before breakfast.
Same thing

Not the same thing.

Above Chris Nagel has illustrated to us how the body consumes our glucose stores during the night.

Furthermore, roadwork is tiresome. The body is tired after it's completion.
Assuming that a professional boxer will train 2 or 3 times a day, periods of rest are needed between workouts - alowing sufficient time for recovery.
The simple fact that 2 hours before training is the optimum meal time portrays the time constraints on a nutritionally concious boxer.
