It's been out for a few years so many have already appeared in the three, but I've just finished a very enjoyable, light read, called One Man and His Bike by Mike Carter.
https://www.goodreads.com/book/show/11745460-one-man-and-his-bikeIn brief, Mr Carter has a good idea one morning on his commute to work in London, which is that it would be interesting to turn right at the northern end of Blackfriars Bridge, rather than continuing on to his office near Kings Cross, and to follow the river out to the sea and then continue around the entire coastline of Britain. A few weeks later, he does just that. It takes him the best part of 6 months.
He's a travel journalist so has a good eye for small details, although reading between the lines I suspect that some of his "encounters" were pencilled in ahead of the trip. That said, it's easy reading, in that Brysonesque way, and effectively balances: an account of the cycle ride itself, various encounters along the way, a bit of local history and personal observations. A good one for a train journey.
