It's the intensity of your riding that will bring forward depletion of glycogen stores.
After that, avoiding blood glucose bonks will come down to how efficent your liver is at GNG.
I never bonk, ketones protect me. My quads tho will run out of glucose if I push too hard anaerobically. If an aerobic workout I can ride all day long and not need food.
What serum ketone levels have you recorded during cycling, or other sustained exercise?
