Far fewer than I used to when commuting between Basingstoke and Reading. I now primarily work from home, but I still have to go into the office because I work in healthcare facilities and you can't really do that totally remotely. So Reading to Basingstoke is about 15 miles, times two is 30 per day, which makes 150 a week (give or take since my parents live near Reading and I occasionally went there overnight, particularly during the recent strikes).
The main port of call is otherwise Windsor, and is effectively twice the difference from home from Reading, so 60 miles round trip, but I tend to cut corners on the way home since a bus from our Windsor office to Slough is just as easy as going back into the centre of Windsor and waiting for a train. I don't think it saves any time, per se, but I tend to get impatient while waiting for transport and also can't stand around for too long due to a gammy ankle. I'd never have thought I'd say this ever but thank god for Slough station. I don't go up that often either -- although next month will be busy as everyone tries to get everything done before the Christmas Party starts.
I do recall hearing that King Charles isn't as fond of Windsor Castle as his mother was, so maybe he'll let me borrow the keys to his flat there when I'm next up. He is, very very very technically speaking, my boss, so...at least it would be better than the Travelodge.
Sigh. A girl can dream, can't she?
