Since I now start and finish all my walks and runs from my house I've been spending some time looking at the map the night before, to find footpaths I've not used before, to link together other footpaths I'm familiar with, to try to get a bit of variety in my routes. So today's walk involved quite a lot of new footpaths. Unfortunately, quite a few of these were over farmers' fields. By the time the mud sticking to the soles of my shoes had reached about 6 inches thick, I was beginning to regret my choice of route. But the real regret kicked in as I started walking past the sewage works. I'd seen it marked on the map, but I wasn't expecting it to be that bad! I tried taking a leaf out of Emil Zatopek's training regime, by holding my breath for as long as possible while I walked. With hindsight, that wasn't such a good idea. All that happened is that when I did need to take a breath it was a large gulp of putrid, fetid air, deep into my lungs. Not to be recommended.
