Re my previous posts (slow, slow, quick, quick, slow). Said I would own up if I had calculated my speed wrong using my pedometer. My nephew has explained to me how the pedometer works and speed and distance depends on your stride. Still don't understand it! Anyway it looks like I am covering about 3.5 miles in 30 minutes. I am still very happy with this taking into account I have only been running about 3 months and I am nearer 70 than 60! Happy running all.
