If I’m doing 60-75 minute pre-breakfast run every other day (upper zone 1 or 75% max HR) should I go fasted, or energy drink before?

Feels fine fasted - am I getting any kind of fat metabolism benefit that would be negated by skulking a load of sugar? Probably 33 to 40g of carbs in a drink.

I’d be having an electrolyte drink before anyway as it’s 30+ degrees here 🙃

I prefer fasted for that type of run as long as I’ve refuelled properly from the previous.

It’s taken me years to realise that I suffer from reactive hypoglycaemia and if I eat too close to running (unless within 5 mins) I feel much worse.
