Normal isn't a very helpful word. It's just not very specific. Sometimes it's what you warmly expect, like a dog greeting you after a long day. Sometimes it's what you lamentably expect, such as any phone call to your cable provider or an airline, predictably painful. Most of the time, it's just everything that happens around you, all that stuff you don't notice. Boring, unremarkable, invisible, unimportant. This kind of normal is everything a bike ride should never be.
