I've not posted for a while but I've kept up the commuting on my three-day week all through a glorious summer in the UK and I think I need to go back to the winter to remember the last time I used the car to get to and from work and it's probably the same length of time since I rode a bike with fenders. My commute is still a very short 3-mile each way and I miss how fit I was when it was 12-mile each way!
Things have just changed in work though and I'm now on a four-day week but working slightly fewer hours due to a shorter working day. On the plus side, my contract has been extended to the end of March 2023 and I think that proper retirement beckons for me then after being semi-retired since December 2018.
