One or two members of this community have alluded to their fondness for, or at least their participation in a spot of road racing. I think Falling Down also suggested that one or two Wad Emeriti indulge from time to time. Now, climbing and cycling are fairly complimentary, in the sense that they don't interfere with each other to any great extent, and you can (if you so wish) train for and/or take part in both on the same day/consecutive days, etc, etc without any particular problems. What I don't get is how anyone could combine proper climbing and proper (ie - Cat 2 and above) road racing without either being a physiological freak or trust-funded full-timer.
Then again, there are plenty of things that I don't get that probably have perfectly rational explanations. It just strikes me that, based on my own experiences of road racing (which sadly consist of getting systematically dropped as soon as anyone decides to go extra fast up a hill) you can't let anything as ridiculous as trying to climb a bit of rock now and again get in the way of lycra-clad bum on saddle...
On a related subject, as I was trundling along this morning it struck me that if had an altercation with Carlos Sastre halfway up a hill and, in a fit of rage, cut one of his legs off with a chainsaw (making sure to cauterise the blood vessels, tie off the femoral artery, etc) he would still be able to ride up the hill considerably faster than me.
