I have no idea how fast anyone 'should' be.

Wait, no, that's not true. I firmly believe that the racers I'm rooting for SHOULD be faster than the ones I am rooting against.

For the rest of us, I have no idea.
For myself, I'm all about longer duration-lower intensity and mostly enjoying the ride.

If you want to ride faster, maintain hydration, increase fitness, lose weight (on your bike and your body) and do other stuff that fast riders do. (Pedal faster?)
