Just to let you know,
@SatNavSaysStraightOn, I was a purely utility cyclist until yesterday. Your blog inspired me, I asked for a book of day-long cycling tours for my birthday, and I did my first 30-miler yesterday. Well, it turned out to be 27.8 miles so I am pretending it was my first 45km-er! It was only local - I had meant to go over to Sandwich* but I'd had a migraine the previous day and was unable to make an early enough start, also thought maybe I shouldn't go too far afield in case it came back. I went on my semi-'bent for comfort and amazed myself but going up a really long hill in reasonable form. I thought the knees/thighs would be punishing me today but they seem ok and I think I might even manage my 10-mile utility ride today (to the opticians).
I suppose I have occasionally gone "out for a little ride" in the past, also I have started to take a few extra loops when commuting, but this was my first proper ride and it was lovely! Thanks!
*Edit: by train I mean - then do a loop over there.
