I second just about word for word what @timg suggested. Yes, each of us is different in our insulin sensitivity and the duration that active insulin stays in our bodies. As I’ve aged, I’ve become more sensitive to insulin but also find that it apparently lingers longer in my body.
As an example for managing, and slightly different from Tim’s suggestion, when I’m headed out for 25 miles on my heavy mountain bike, I lower my pump basal to about 25% at least an hour before I begin peddling and always have a complex carb such as English muffin with PB just before my ride. While riding, I hydrate using a reduced strength Gatorade [I use the powder] and check my BG frequently and if necessary eat a small granola bar that has total 17 grams of carb with only 7 of those carbs being sugar. I very rarely have a “sugar spike” with this routine.
Something I have learned after much trial and error is that I need to send a signal to my body, yes trick my body into believing everything is normal activity for me. By the time I finish my ride, I usually stop a couple of miles out, I check BG and eat a snack WITH insulin - usually 2/3 the insulin I have for that snack. Somehow this signals my liver to start releasing glucagon; I don’t know how this works, but for me it mostly has solved the very low BG I’d experience, like those of your daughter, in the evening.
