Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

It's not an opinion. It's documented fact. You can store muscle glycogen for about 2 hours worth of riding.

If you're riding hard enough, and don't eat anything, you'll be down to just burning fat after 2 hours, and you'll be slow, and uncomfortable from that point forward.

Admiitedly, it would take a pretty intense effort to bonk in 2hours, but if you spend the majority of that 2 hours at or above threshold, you can do it.
