That moment when you go from cycling into a headwind, to a tailwind, match the wind speed and suddenly everything is eerily calm.

Saying hi to fellow cyclists and joggers.

Being able to use any one of the half dozen routes to work, depending on how much time I've got.

Being able to 'take the long way' home, to get extra miles in.

The steady reduction in my commute times as I get fitter.

Knowing my commute by bike is quicker than my old bus & train commute.
