    With all the talk regarding this year's TDF speeds, I found this website http://www.torelli.com/raceinfo/tdf/tdfstats.html
    and did some quick calculations. This may have been done here before, but I did not see or get a search return? Results are listed below, draw your own conclusions.

    Years ..........%change in avg. speed (km/hr)........Avg. length of tour(km)
    1903-13............ +4.034........................................ 4229
    1914-24............ -9.633 ........................................ 5445
    1925-35............ +23.489 ...................................... 4398
    1936-47 ........... +.977.......................................... 4424
    1948-58 ........... +10.397....................................... 4655
    1959-69 ........... -.183........................................... 4340
    1970-80 ........... -1.250......................................... 3962
    1981-91 ........... -.547........................................... 3784
    1992-02 ............ +1.078........................................ 3736
    2003-05............. +1.744........................................ 3475

    Be careful with comparisons, overall race distance changed over time, sometimes rather quickly and drastically. World wars intervened, etc.
    Not a scientific comparison!
