On reading this this morning I know just how they feel. Our house is on the River Lea Navigation. Since lock down, going for my daily exercise walk. which I did before lockdown, has become a really unpleasant, stressful experience. The tow paths are like an Olympic training route for runners and cyclists. You cannot walk them and keep social distance. I have spent the past few months trying different routes around my village, trying, as requested by Canal and river trust, not to use the towpath unless for local use. As a local, I, unlike many of the users, do not need maps and satnav to know where I am and how far they still have to go for London in one direction and Hertford in the other. All this has been going on since the beginning of lockdown.
