Average Speed Usually Isn't
I know cyclists like to use average speed as a benchmark. However, benchmarks by definition are not accurate. The problem is that most use moving time to figure average speed. This invites all sorts of fudging, if not actual deception. The only way average speed has any kind of meaning is if moving time is equal to elapsed time. Only then can one claim true average speed.
I am temporarily located in an area where I can, and sometimes do, ride for 2 hours without stopping. In those cases I am moving the entire elapsed time of a ride. I don't unclip, and no, I can't do a track stand. Thus, I have been able to calculate true average speed on these rides.
Get some popcorn and discuss..
