I too am a veteren. I ran my first marathon in 1978. I ran a 2:58:34 (still my PR) in 1981.
Some of the younger guys don't remember how Dave Costill and other exercise physiologist were saying that glucose drinks didn't help, how you don't need to eat breakfast, how calories you eat on the run never make it to your muscles.
The think they might be right--the carbohydrate might not make it to your muscles--but the Wall is as much about running out of BLOOD glucose as about running out of muscle glycogen. And the glucose drinks and gels DO get carbohydrate into the blood stream.
As a biochemist, I hate to say that experience is sometimes better than experiment, but such is the case when it comes to running marathons.
