    For my first hit on Google, I come up with:
    Average Speed Cruising Speed **
    Class A 21 20-22
    Class B+ 19 18-20
    Class B 17 16-18


    [etc]

    There is something pretty funny about these numbers anyway. In all but the
    flattest terrain, the average speed is lower than the cruising speed
    range.

    My omission.

    At the bottom of the chart there is this:
    -------------------------------------------
    * Average speed is while bicycle is moving.
    ** Cruising speed is the speed a cyclist should be able to maintain on a flat
    terrain with little wind. Speed will vary with grade, wind and distance.

    Yes, that's exactly what I mean. Anywhere but Cambridgeshire [1], I expect
    the average speed to be less than the range of cruising speeds. For
    example I commute at a cruising speed of around 21mph; this produces an
    average speed of 17mph, because although I can sustain 21mph on the flat
    easily [2] my average speed is reduced by hills.

    So "cruising 18-20, average 19" doesn't make any sense.

    [1] Utah, if you like. Somewhere dead flat.
    [2] When I haven't just broken my jaw and had tonsillitis. :-)
