Well I've just completed the run...........and have to say I'm pretty knackered.
But no wonder, looking on map my walk it seems I've done 40 minutes in total!!? I have to say I thought I waited a long time to get my 1st and 2nd update from 'Laura' so not sure if phone got unlocked in pocket or fault somewhere. But anyway the main thing is I completed the run (+ a bit more!).
