Do you?....
Whilst riding on your own or with a friend do you try and chase down a rider you can see in the distance? Then, when you've caught up and pass you stop huffing and puffing, pretend it's a breeze, nod or say 'G'day, nice day for it' as they struggle. THEN once past huff and puff and nearly cough up a lung trying to stay ahead and increase the distance.
There's gotta be some other riders out there with some cycling confessions about wankerish or amusing things you do.
It's time to confess....
Here's another one I do. When doing a group ride I pretend to be more tired than I really am so I don't do my turn on the front. THEN, when it's time for a sprint I surge ahead and then say 'I don't know where that came from'.
