Can someone please explain to me why so many of you are still pedaling around in sub-zero temperatures like a bunch of lunatics, completely oblivious to the fact that your energy expenditure is skyrocketing with every pedal stroke? I mean, seriously, do you guys not care that your body is working overtime just to stay warm? Dont you realize that for every degree the temperature drops, your energy expenditure increases by a significant margin? Its not like its rocket science or anything. So, Id love to hear from all you cold-weather cycling enthusiasts out there - how do you account for the massive energy drain of riding in the cold? Do you just not care about efficiency, or are you all secretly trying to burn off last nights pizza?
