It was such a wonderful day for it. London in all its splendour!
We had to take a little detour around Woodberry Wetlands because the road was closed to runners (https://www.wildlondon.org.uk/nature-reserves/woodberry-wetlands) other than that we followed the traditional route starting near Stratford and ending around Waterloo.
I run with my partner all the way. We never stopped and carried all we needed ourselves.
