Ah. Cycling.
I was a 4-digit UMCA member, competed in numerous 12 hour, 24 hour, and state-crossing events, thought nothing of riding four competitive centuries in four consecutive days, was invited to join one of the Race Across America teams, and my hundred mile time trial PR (no drafting) was 4hr, 28min, 51sec.
(The fun part about cycling is aerodynamic drag is a square function, but the power needed to
overcome aerodynamic drag is a
cube function... and
you are the power source)
Imagine my joy when I was told by the Doctor Squad that some body chemistry shit had gone haywire and my bones had become fragile, and any future breaks might never heal. (The situation was stabilized but can't be reversed) No more riding for
moi, just like that.
