'Source to Sea,' a Walk

Waterstones

Isolated as we are, banned from walking the earth as we wish, and quite simply unable to hike 215 miles alongside a river this book is a good way to get ourselves outside, in comfort.  
The author, a Londoner who lives and works close by the river, decided one day to leave the travel desk at the 'Times' and travel along the river, from 'source to sea,' thus providing himself with a title and some blisters.  Walking from pub to pub, with occasional hotels, for rest spaces he completed the task covering 368 miles in 21 days.  His detours, not always deliberate, added to the length of the journey.
What can be said about a walk by a river?
The early stages cover paths blessed by a wide variety of flowers and wildlife, cattle, horses or sheep appear in fields around, swans and sucks paddle past often silently.  The stopping places and foodstuffs get good coverage, some would say too much but if you follow the trail you will see this as wise advice or warnings.  Old pubs often go back several hundred years, all have their tales of famous or infamous deeds and people, some of them true.  Occasional houses, usually for the very rich, are passed all along the line of the river.  Near the beginning gardens from aged cottages costing a million reach down to the waterline, often with boats at the ready.  Near the ending London apartments cost double that with views of the river front and former warehouses turned into just as expensive flats.  Neither indicate prices we can afford.
From the bird covered countryside London appears, as do industrial estates, lower priced housing and dereliction.  You will note I miss out Reading!  "One does not linger in the neighbourhood of Reading," wrote Jerome K. Jerome, out Tom considers this good advice!
I'm torn with wanting more descriptions of the house, churches and past sights throughout the book while being somewhat bored with the repetitious nature of much of the writing.  It must be difficult taking notes on such a walk and even more difficult to find new ways of describing similar daily experiences.  The fact that so many historical or interesting places, events, situations arise on such a walk along a river that has seen two thousand years of history, more than that we cannot discover much about, means there are several books to be made from such a walk, possibly half a dozen at least all the way along the river.  
I could be being greedy of course.
Eventually, having wandered through London itself, again the contrast between the rich and the poor appears, he snakes his way to the finish a black stone that marks the official end of the river authority and the beginning of the North Sea.  Two stones, one at either end mark the course, one at the sea the first in a dry field!  Later in the year it is wet they say!  From this trickle that cannot be found to the far end the book holds out attention, not least for his honest descriptions of those he meets.  Several bars are to be avoided, some to be looked out for.  
This is the type of book I wish I had written, although it must be said the grammar is better in this book.  However I have not made such a journey in recent years, I am unlikely to make one soon, unless a description of walking early to Tesco will do?  I recommend this book a s worth a look for those who are trapped indoors, like rivers and pub food and have 'spare time' to read...
