Then again, sometimes, you just have a bad day. There are days where I have gone out and feel like I'm going to die... and other days where I fly along.
You have to figure out what works for you nutrition wise. I will say that cardio on a bike is less jarring and thus easier to consume food before/during, without getting sick or cramps from it.
