"We start our stopwatch at
a pre-determined point, where the
2009 Tour’s difficulties begin. We
stop it at the summit. Our measures
take into account obscure, but no
less important parameters, such as
frontal area, the coefficient of rolling
resistance, slope grade, and average
air density. It’s amazing to identify
“greatness” just sitting on a couch.
The kind of greatness that breaks
the 1.1 cyclopower barrier: 450
watts. That’s the Tour for you. I’ll skip
over other scientific considerations,
which rely on knowledge of human
physiology, like maximum VO2, the
endurance index, assorted biology,
and so forth. "
