Sam uses fast-acting insulin before meals, and long-acting insulin at 8pm.  He often goes for a run before breakfast during the week which is usually around 7-8am. When he finishes he gets ready for college then has his breakfast  and normal fast-acting insulin dose before he leaves the house. He has noticed he starts his run with a good blood glucose but by the time he finishes he has risen quite high, which he doesn’t understand as exercise should make him go hypo. Then by lunchtime he is often hypo or around 4mmol/l.
