Hi, I'm a keen hill runner and have been finding it difficult to race in hill races lasting over an hour, even with extensive long runs in training. I struggle, as it seems I run out of glycogen and haven't been able to replace/maintain it during a race. I have tried using the lowest dose of insulin I can and even no fast acting insulin at all but my sugar levels drop too far and cause a drastic drop in pace. I have tried to see if using gels and drinks to maintain blood glucose levels during races but nothing seems to work predictably. Hypos only become a problem during races and can be managed during training runs. This only happens in hill races as running road races doesn't cause the same problems. How can a diabetic runner absorb glucose during a race, without risking a hypo?
