All runs are different, and the one today was no exception.
It was yet another of those times where it took me pretty much exactly half an hour - and half the distance - to feel any kind of flow and energy. The strange thing is that I know this happens to various degrees pretty often, and yet I still doubt it in the beginning, and find it surprising when I pass that point into a bit of flow.
I found the flow to such a degree that I think the second half was quite a bit faster than last time I ran the same distance, even though I felt much stronger and faster overall that time.
Sticking with stuff pays off. It is kind of my thing, really. And yet I still do not quite manage to trust that it is how things work.
