yup, been cycle-commuting all year round for six years now. 18 miles (28km) each way for me, 7,500 miles (12,000 km) per annum.
For the last few weeks have been extending my route home to 25 miles just cos I can.
Once you do it as long as i have it becomes second nature and it’s more painful to get the train/tube.
Decent kit is the most important thing, there’s no such thing as bad weather etc.
Was nice and windy today and CS7 was rammed due to the tube strike but I still enjoyed it.
Edit: Oh, and mudguards, Crud Roadracer II’s make a big, big difference to the whole winter experience. Add them to an old road bike that you don’t care about whether it gets ruined or not and jobs a good’un.
