If it was a proper bonk then you definitely didn't eat enough. I was reading somewhere that bonking is classed as a "medical emergency" and it takes a good week to recover from it. I properly bonked once - all of a sudden I couldn't pedal at all. Even going downhill was an effort. I was woozy, a little bit delirious, and no matter what I did, the legs didn't want to respond. At all. After stopping at a convenience store and stuffing my face with chocolate bars and energy drinks, I got home and proceeded to eat the fridge.
If it was a "oh man, I'm really tired and I don't want to go on anymore, I'm suffering" then it could be a number of factors. Not eating enough is high on the list. If it's hot and humid, a sports drink is going to be more beneficial to you than water as you get both carbs and salt. I don't do well in the heat so if I underhydrate I cramp big stylie.
Take stuff to eat and drink on the ride as well - my on-bike fuelling strategies are posted somewhere else. If I eat properly on the bike then when I get home I'll eat a bigger lunch/dinner than normal and then normally for the rest of the day. If not, then anything's fair game.
You may want to recompute your cal intake on Spark just to make sure that you're eating enough too. You could eat at the top end of the range when you ride long and at the middle/bottom end when you don't?

If God invented marathons to keep people from doing anything more stupid, the triathlon must have taken Him completely by surprise.
