Is that in Ironman distance event? You are brave! A colleague completed one last year: He was fine on the swim and cycle but took 8 hours to walk the marathon, stopping to throw up every other mile. It put him off doing a marathon again
If you want to avoid his fate you will need to focus on training your stomach to take on fuel during the event. It's a very individual and tricky thing to get right as different things work for different people.
I honestly don't know how people have the time to train for an ironman. Marathon training took up most of my free time so fitting in cycling and swimming training too would be all consuming!
I think you're mental, but best of luck
