I just finished a 21.58km cycling that lasted about 1hh:4mm:46ss !
I'm not sure how much longer I'll be commuting to work as the nights are getting longer and the weather is slowly getting colder. The cold is not really an issue but as there is less daylight, riding in the dark in Auckland can be pretty unsafe so I tend to stop this when the winter starts to come in.
I set the goal for the end of March and it is looking like I will make it and it has really improved my riding and fitness as a result. Really hope I can maintain it over the winter though.
