I got a new warmer walking coat lately, that makes walking practical in somewhat colder conditions than previously. After a five-miler around Becontree and Chadwell Heath to make sure I could do it, I engaged on Friday in the longest batch of walking in my life - 11 miles on this stretch, with a total of nearly 16 for the entire day.
That included the long Elizabeth Line-Tube interchange at Heathrow Terminals 1, 2 & 3. Well, really 2 & 3 as Terminal 1 has closed.
These two sections go from Hatton Cross via Hayes to Uxbridge, mostly along the River Colne and the Grand Union Canal. It doesn't start very nicely:
It took me around six hours overall, including the lunch break.
