Survival of the fittest: On the way to work today it struck me that all cyclists would do well to realise that we are not competing against each other. I have some fairly nasty encounters with other cyclists lately. Asking people nicely to move out of my way so I can get past because I am fitter than them and can move faster than 1 mile an hour – the abuse! Many mornings as I weave my way through the crazed commuters aroung Stephen’s Green I feel like shouting to the other cyclists: “C’mon! Critical mass! Critical mass!” but I know they might not understand.
