Accommodate your stomach while you run
Experiment with the type of fueling that works best for you. Everyone's body reacts in a different way, and when it comes to having IBD, your digestive system is even more sensitive than most people. Some find it best to run on an empty stomach and drinking the absolute minimum amount of water to stay hydrated. However, others think it’s best to go with a lot of water and eating small meals prior. Everyone's going to be different, so you're going to have to feel for what your body feels most comfortable with.
