NOTHING NEW ON RACE DAY gives general information about endurance fueling. It is not medical or dietetic advice, it does not know your medical history beyond what you tell it, and it is not a substitute for a clinician who does. If you have a health condition, are pregnant, or take medication, talk to your doctor or a dietitian before changing what you eat and drink around exercise.
