Here’s some great advice from someone who knows. Her name is Cathy. She lives in Australia. And she’s a great London walker. As well as a good friend. Here’s Cathy’s advice: “Hot weather…expend little energy, a cool wet flannel on the back of your neck is amazing, drink water all!!!!! day – more water than you think you need! And air con on max from first thing in morning before the house heats up.”
Many thanks, Cathy. All good to go with all of them EXCEPT the last one. Pretty much no one over here’s got air con. But the thought counts for a lot. Much appreciated.
