I'm training for IM AZ and did my longest brick since 2010 yesterday: 5.5 hour ride, 1 hour run. I drank 4 bottles of Infinit, and ate 7 PowerBar gels and 1 bag of PowerBar gummies. I had my normal protein shake and post-workout meal/snacks after. Later last night, my stomach started feeling really weird. The best way I can describe it is that it felt like a hangover stomachache. Sort of nauseated, but I never actually got sick. It kept me up most of the night and still felt the same way this morning... I don't eat a lot of desserts/sugary foods, so I am trying to figure out if my body wasn't used to all that sugar? I used the same drink/gels while training for 70.3 races earlier this season, and it seemed like a good combo and I never had any issues like this before. Of course, I was probably only going through about half the quantity since the workouts were shorter. When I trained for Louisville in 2010, I used a mix of Hammer Perpetuem, electrolyte drinks, gels, and Clif Bars and never had an issue like this and am thinking I might go back to that- maybe the protein and solid food helped to dilute out the sugar?

Has this ever happened to anyone else? Any thoughts or suggestions are much appreciated... thanks!!
