I've been on some long trips, but never really paid attention. What are people's experience with how long a highway run (keep it longer than 6 hours) actually takes compared to Google maps estimate? Like for instance, Google maps says 12 hours. You probably ride a little faster than the speed limit, but stop for gas, stretch, coffee, lunch, etc. I'm not talking scenic routes, but when you are straight traveling to go somewhere on the bike? Not counting mechanical failures, horrific traffic or overnight stops.
