Reading Southern Softie's interesting BLOG I noticed that he had a lot of food organised for his ultra but ended up feeling pogged and not eating as much as intended. I have just been listening to a Jeff Galloway PODCAST where he asserts that while running marathons (unlike cycling, football etc) one can only absorb c.40 calories and 2-4oz fluid per 2 miles because the digestive system is almost shut down. Has anyone found they can eat and or drink more than that, while running long distances, without ill effects?
