On Sunday, I downloaded the written details (thanks to all for help and support) and within moments the heavens opened, so first rush of enthusiasm was washed away. Never mind.
Monday was forecast to be wet for most of the day, so went swimming first thing and did 50 lengths, which I hadn't done for a while and which I felt was enough for one day, so that was Monday.
Tuesday, this is it! Sun and clouds, gentle breeze. Off to the village playing fields, which are, quite conveniently about a 5 minutes brisk walk away. Surprisingly, for a nice day in the school holidays, there were few people about - and, believe me, I did not want an audience! Thankfully, also, only a couple of well supervised dogs. Because I don't use headphones, I had decided to work on running 120 paces, walking 180. A couple of timed runs around the garden had indicated that jogging 60 paces took me just over 25 seconds, so 120 paces could be one minute, so off I went. And, blow me, it was hard, but I made the first 120 and then relished every moment of of the 180 walking steps. But, what do you mean, "that's not it, I have to do it all over again"? Actually second time was easier. Third, fourth and fifth, not too bad. But in this little patch of Middle England, the clouds cleared, the breeze dropped, the sweat trickled down my forehead and, I admit it, I gave up. Perhaps 15 minutes, rather than 20, but at least I started. Swimming tomorrow, then the weather doesn't look too bad for Thursday.
