Diet

you cant bonk from doing nothing ,if you think you are youve never had it properly it is the most feared thing when i ride a bike.Last time I had it I went cross eyed and wanted to fall in a ditch,it took me over a week to recover.Feeling hungry and getting the knock are worlds apart

I beg to differ. The main problematic symptoms of "bonking" when doing sports is the dizziness/faintless/risk of unconsciousness that comes from becoming hypoglycaemic. But with depleted localised muscle glycogen thrown into the mix. The latter is no big deal. The former is just the same as if somebody becoming hypo for any other reason.
