I know its crazy but on several occasions I have run out of energy going home, its only 15 miles each way and a usualy 18 mph, but you get that feeling, that your legs go, I get al cold all of a sudden and drop to 8 mph and then eat my emergency snickers bar then 10 mins later its back to normal.
Not a genuine bonk, then. Just an inability of your body to process the glycogen to energy. Either you have a genuine medical problem (diabetes, ME or something - I'm no expert), or its a hydration problem, or you just need to train through it. Remember exercise makes you tired. That is what it is there for.
