I won't actually write the swear word in case it offends some of my readers!
I did a run today that was 3 miles according to the milometer on my bicycle. My pedometer said it was 3.6 miles. Which might mean I have been covering less distance than I thought.
Hopefully my milometer on my bicycle is wrong, although this seems more unlikely than the pedometer being wrong.
My brother in law has some kind of snazzy satellite navigation thing that he uses while mountain-biking that gives an accurate mileage. I'm going to see if I can borrow it to put my mind at rest.
The short run was hard work today. My feet ached all the way round and I felt so stiff. I am beginning to feel a little despondent but I will fight it!!
