CGM summary graph for case 3. This 18-year-old male used RT-CGM while training for and competing in an Ironman Triathlon, 13 hours of intense physical activity. Although he was hyperglycemic at the start of the biking event, CGM showed his blood sugar began to drop rapidly (arrow). He consumed up to 75 grams of carbohydrates per hour while biking to avoid symptomatic hypoglycemia later on during the running event of the race.
