that happened to me yesterday. had some coffee about an hour before
my run and i swear i could literally feel the liquid moving from
left to right in my tummy with every step i take!
It was worse during Sundown last year.....
I was rapidly losing fluids through perspiration.... so I made
up for it by guzzling down lots of 100 Plus along the way.....
Unfortunately, my digestive system seemed to have shut down, for
all that fluid was sloshing around in my stomach without getting
absorbed. So for much of the way, I had severe leg cramps (due to
lack of electrolytes) combined with a stomach with
constantly-sloshing electrolyte-heavy contents that refuse to get
absorbed.
Even after the race (and more guzzling of fluids) it took a few
hours before I could finally pee.
And when I did, phew, did it stink to high heaven......
