Struggle, as meaning struggle to digest, or struggle to get down one's
throat? I can't say that I can recall ever struggling to digest
anything,

Then you're not running fast enough (or far enough). ;-)

I would say, if anything, on trail races (with aid stns at fixed intervals) I tend to start to fast and not eat enough in the early stages of the race. I don't get overtaken at aid stns because I only ever stop to eat but others stop to pick about at their feet, change the shoes and so on. I do unfortunately get overtaken on the trail. It's different on track races where there is usually a constant supply of nibbles. If I were running 6 mph on the track I would have no difficulty in digesting food. My legs would give way before my stomach. On races with hills, I walk up the hills anyway.


Seriously, I've yet to meet an ultra runner who hasn't had digestive
problems as some point or other. It's a simple fact of physiology that when
you exercising, your body has to choose between sending blood to your
stomach or to your legs. If you have sufficient cardiac reserves, (and that
depends on your fitness and your speed) you will digest a certain amount of
food but your digestive abilities whilst running are definitely compromised.

It's very simple. My body is conditioned to prioritise in favour of my stomach. I have a whale of a race and do a crapp time.

(Note the correct spelling of the word crapp with 2 p's.)
