Oh good grief...
I did say I had long walks sussed, didn't I? I did do 20+ miles in one walk, with only scheduled stops and no hypos only three days ago? Good job I'm well aware "sussed" only ever means for that day!
Today's shenanigans after 5 miles were made ever so slightly worse by me disbelieving the 4.7 and thinking I could get to the next bus stop, no bother. Which I would have done if the bus company hadn't decided to put that stop out of use. One on a critical interchange point in my part of the world. It's going to be dreadful when the schools go back as lots of pupils swap off the circular route on to my route there (and vice versa) as there are a lot of secondary schools along both routes. So, another 4 minutes walk and "Hello hypo". Three attempts over half an hour it took to get it above 5 again and the best part of a whole packet of Dextro!! Of course, by the time I did get on a bus and home, I was up on 10. But a brisk 45 minutes gardening sorted that one out.
Normally I run high on a Sunday, today's been a struggle to keep above 5.
