I disagree - like the Cascade rides I would classify rides based on speed for flat ground without breaks because 1. most people over estimate their own average speeds because they look at the speedo more often when they are going faster and 2. average speed is usually a bit of a liar - many of my training rides clock in around 15mph if you look at the computer average at the end of the ride, but that counts many stop signs and other things that bring that average down. The rides themselves are actually much harder with the flat ground averages being more like 18 - 22 mph...
