How about when the old guy picks you out to race against and he takes off on you and for a moment he is 27 again.
I think that it's all in the mind as a indoor cycling class. Feel free take off and attack and attack again when you cross the line you have an interview with Bob Roll

I have a riding partner that I race against he makes a foreward move and then I will -each of us not trying to show we are sucking wind while the other catches up. Some days its my day some days it's his.

You are only as good as your next ride
