...especially as my leg had ached a little bit in the night, but down to a problem with the gel insoles in my hiking boot yesterday - not quite trimmed to size.
So I put on my long compression socks and set off. No problem with my leg although I wasn't quite happy with my run until Laura said I had done 5 minutes, then it was fine. I ran a bit slower than usual I think but kept it steady and it went well.
I tracked the route on the fitbit app on my phone. A bit odd as is showed I ran a straight line from the transmitter mast to the point I finished the 5 minute warm up. (presumably leaping over garden fences and possibly through the front door and out of the back door of some houses that got in my way!) I assume that it took that long to find my location - I don't switch it one very often. But no matter, it tracked the run and confirmed what I had worked out while I was going round this morning - the mown tracks on the meadow form a four-leaved clover!
It claimed 4.03 km for the whole session - my pedometer said 4.63, which included having to go upstairs to get my sunglasses before I started! So not wildly out, I did calibrate the pedometer against 5 x 100m markers yesterday while I was out for a walk and found it is measuring very slightly less than it should.
So in the end it was a good run.
