IM after GI illness

Crappy timing. 

BRAT is good, bananas rice, apples, toast.  Also gatorade.  Try to avoid foods harder to digest like oily/greasy foods or high fibre foods.

I had tummy troubles once a few days before a race, race day I was fine, granted it wasn't an IM.  I would also start taking something for the GI issues if you haven't already.

Yup, this.   I hope you get better quick and have a great race!! 

Hope you improve quickly Kathy!

Unfortunately, I have personal experience with this.  Here's my IM MontTremblant report from this year:

You have a few days to recover.  Get some calories, get sleep, and dont stress about the race outcome (easier said than done ).  You might try some of the pro-biotic type pills to re-populate the intestinal flora -- they can take a big hit from GI illness. 

During the race, focus on good execution, esp nutrition.  

You'll have a great race! 

Same thing happened to me two years ago. In addition to the above advice I would also suggest that you try to hydrate as much as possible today. I ended up with tendonitis (adductor) likely because I was dehydrated from the stomach flu.

Good luck in your race.

I know this is a little late since the race is tomorrow but if you can get some IV fluids in you do it. Get hydrated.  I had a food poisoning last year before a HIM and ended up in the med tent because I couldnt get re-hydrated before the race. Never made it out of T2.  

Good luck
