What is the ideal sugar level before, during, and after a long run? how do you prevent sugar low during the run? any advice on glucose tablet dosage?

Questions: Do you have diabetes? Treatment with oral meds or insulin? In our Insulin dependent kids, we lower Insulin ahead of time and often for hours later. We always ask them to carry glucose tablets or some other form of fast acting glucose and to stay well-hydrated. We also help to modify before and after meals if necessary. Most important: medication adjustment which has to be done by you & doctor.
