Yesterday I did my first 100k, a full supported ride with 3 full rest-stops and a water stop if ya wanted, SAG, the works.
It was all I could do to force down some fruit at the rest stops, and consume all of my gels (5) for the ride. This made me very tired near the end. I knew what my problem was, I just felt nauseated at the very thought of eating anything other than some grapes and pineapple.
This is an ongoing problem and I don't know how to solve it. My stomach simply rejects (eat and then thrown up) solid food when I am exerting myself, and I lose interest in eating food until a couple of hours after the ride has been completed, as if it just shuts itself off and will not accept new input until it is sure no more exertion is to be done.
Does anyone else experience this? Why does this happen? And what can I do to prevent or at least attenuate this? I'd like to do a century later this year or maybe next year, but not if I can't eat real food at regular intervals to keep the body fueled.
