    Your calculation seems quite wrong: it's easy to push 150 watts on
    exercise bicycles, and I can sustain 300 watts for a short while.

    Daily calorie intake for a professional cyclist (during a long, 3-weeks
    race) is around 7,000 calories, but we are speaking about people
    capable of generating 400-500 watts for hours.

    I suspect you got caught in the (big) "Cal" and (small) "cal" trap: both
    are calories, but the former is 1,000 times as big. Of course, the RDA
    are expressed in (big) Calories.

    Ciao,
