Sir Edmund Hillary's first words to lifelong friend George Lowe upon returning from the first successful summit of Mt Everest in the company of Tenzing Norgay were...
Well, George, we knocked the bastard off.
Later he expressed great regret to his mother for the embarrassment she felt as a result of his infamous declaration. Taking inspiration from his epic feat, I have found it a great way to announce the impending completion of some not-so-epic, but still a reasonable challenge. That said, I do try to be sparse with it, saving it for the end of truly hard rides like a 24 hour fleche or a double century on mountainous dirt roads. Usually, just as we are about to start the last leg, I'll suggest we "get on with it and knock the bastard off."
But after my latest challenge, the Rapha Festive 500 on my indoor trainer, I might just have to retire my use of that phrase in the future! But, by George, I knocked the bastard off!
