The only thing I can add to the advice is to register every year with the Tour de Cure in your region and ride on weekends with your local Tour de Cure training group; the Tour de Cure is the annual bike event that raises money for the American Diabetes Association. Many of the registered cyclists are diabetics, and many with type 1 diabetes, and I know the type 1 diabetics have it figured out because they ride long and hard. If you join the weekend training group, you will meet other type 1 cyclists and can ask them questions and learn from them how they solved their blood sugar problems. You also get a free Red Jersey that tells everyone you ride with diabetes for the American Diabetes Associatioin.
