Has this been discussed in the podcast? Maybe someone can point me to the episode.
Generally I’d say I have a strong stomach. I’ve never thrown up during a workout and can go a long ways on the bike eating junk food without stomach issues. In many years of racing I’ve had one instance where I needed to stop to avoid diarrhea disaster…halfway through a full IM run and it was either walk or explode, so I chose to walk and spent the next 13+ miles running (slowly) from portajohn to portajohn. Cost me a Kona slot in that one, oh well. Wrote that off to not eating my typical pre-race meal the night before, and probably too much fiber/food that morning.
Few weeks ago I went out for a 2x8min FTP test and had a very similar feeling about 4 minutes in. Had to pull the plug on those at 5-6mins to avoid a humiliating end. Same feeling came on today during 130% efforts, though was able to complete the whole thing as prescribed.
Is this the same as the common “runners trots” even though there’s not the sloshing of running going on. Perhaps simply more time between the last bite of food and the workout, as well as eating less fibrous foods beforehand? (I eat vegan/plant based, so no dairy…but lots of fiber)
Any sciencey stuff or personal anecdotes for what works and what doesn’t?
