Eh, it's always slow for me, I bike between 15-20mph based on weather, google maps estimates 11ish. But my real issue with it is the bike 'safe' routes it picks for me. I normally end up doing a car route, but turning on the 'no highways' option, otherwise it'll add 20/30% extra distance while it tries to route me around 'unsafe' roads or over to out of the way bike paths.
