I always run in the morning, before breakfast and this works really well for me.
Last week I went swimming on a rest day in the afternoon 1.5 to 2 hours after eating and afterwards I felt dreadful my blood sugar levels must have really dropped as I was shaking and felt awful. I wasn't dehydrated but didn't have any carbs for lunch, mainly protein although I did have a large bowl of cereal for breakfast.
So, I'm concerned now that if I go running in the afternoon/evening I'll start to feel like this and won't be able to complete a run. Maybe the answer is to eat carbs at lunch?
I don't want to be limited to just running in the morning - any advice gratefully received
