Well done, that's an impressive feat.
I also sold my car a few years ago, so I can say categorically that it helps to live somewhere that accessible on foot or has decent public transportation as a back-up option is very helpful. I cycle 11 miles TW9-SE1 in London, but these days I only do it when the roads are dry (safety and comfort), and take public transport if I'm feeling unwell, need a rest, have plans elsewhere during the day/after work. I also sleep like a baby after three days in a row commuting on the bike, which is great for an insomniac like me.
Keep up the good work, keep yourself feeling good, and keep safe.
