I did the first run today. In both the first and second five minutes I realised I was speeding up (both times just before Laura announced the halfway time).
As usual I found the final run easier than the others, although I was pleased to be told to finish.
Yesterday I came across my pedometer so used that as well. 4821 steps, 4.09 km does that sound about right?
So, toughest so far, but doable.
I am not expecting to have wifi from tomorrow to Monday, no idea what, if anything I will be able to report then as I don't know whether I will be able to run anywhere from the campsite, but I will try to continue with Stretch & Flex.
