Today's run was kind of mixed up from the get-go.
I had a good signal to iPod link at six when I woke.The blue tooth GPS sender was fully charged so I switched it off to save batteries for later.
around 10:00 when I was hoping to have an easy lock, no joy!
I tried various combinations of re-booting the 'pod and switching the transmitter on and off a few times. I ended up just doing the two hour run from memory and then measuring it on the Daily Mile mapping tool.(18.68K).
I was happy with that.
