    I think you’re joking, but in case you aren’t, the answer is: no. Digestion takes a surprising amount of energy from your body. You can either use that energy for running OR digestion, not both at the same time. If you are trying to full speed sprint after eating a meal, your parasympathetic nervous system would assume you’ve decided that running at top speed is more important and shut down digestion freeing up energy to use your muscles for running. It might also decide that having the undigested food in you may be a risk, and cause you to throw up.
