Apologies again, I forgot the url codes. I think I need to find a forum on how to correctly add to a forum.
Below is the correct link that should work.

Apologies ref my recent post FIGHTING NAUSEA DEMONS IN AN ULTRA I forgot the link http://www.succeedscaps.com/articles/fighting_nausea_demons_in_an_ultra/

A very interesting article from Scientist and Ultra Runner Karl King "FIGHTING NAUSEA DEMONS IN AN ULTRA" may well be relevant.

"Some people theorize that the body?s feedback mechanisms intentionally cause vomiting as a way to reduce blood pressure. So, if you vomit during or after exercise, perhaps you?ve been working out at max heart-rate for too long."

Good luck!

Have you read the thread "Sickness on overnight walks" that attracted some discussion here a couple of months ago? - it sounds as though your problem is a pretty similar one (and, if nothing else, demonstrates that you are far from alone in feeling this way).

Has anybody or is any body experiencing upset stomach after a certain distance into a long distance event, i had to pull out of the ldwa 100 this year because of feeling bloated/slightly sicky feeling and cannot eat, this has been getting worse over the last couple of years, i did the wenlock 50 last weekend and was fine till craven arms at the 26ish stage, i ate quite alot there as checks were few and far between but from then on i was uncomfortable, i tried coke to settle stomach it helped but didnt clear problem, i managed to finish but i doubt i,d have finished if it had been much further,any advice out there please
