It was going well, a mile walked; a mile run without ANY walking (and uphill at the end).
I was just struggling up a steep bit of road a little old lady was just standing at the top of her drive with her zimmer frame. She called out to me so I went up to her rather breathlessly and she asked if I was going to the shops - I am not sure where I was concealing my purse and shopping bag in my lycra, but I said I was passing, so she asked me to get her some fruit pastilles!
So an extra undulation 0.2 miles each way and my good deed done.
I am not sure how long she had been waiting for a passer by. She could have been there some time as not that many people walk, they all travel by car - I didn't see any other pedestrians along most of that road - maybe she was much younger when she first went out there!
Anyway 4 miles done.
