It's all about trial and error. It took me a good 12 months to work out something that my gut could handle and I still don't think I have mastered my nutrition by any means. And its not just a case of trying a gel and seeing if that particular type of nutrition works for you or not. I tried 4 different types of gel before I finally found something that I think worked. Be creative with different brands and types of nutrition now while you still have the chance. The biggest issue is the run and how it turns your gut into a cement mixer. If you have the time always do a short run after a cycle, even a spin class. Take some sort of nutrition beforehand and see how you feel during and after the exercise. If you are only able to do a short run increase the intensity as this will shift blood from your gut to your working muscles. It might sound steep to take a R20 gel after a spin class at a Virgin Active but in the end a couple of hundred rand testing different products may just make or break your race.
