Sloppy Intervals
I just finished a 5.506km running that lasted about 0hh:39mm:58ss !

I took the hint from @steevc and used an interval timing app instead of trying to reset two times for every set of intervals. But somehow I didn't hear the beep announcing the second set and so walked too far then tried to run a bit and realised I needed to just stick with the structure. So I ran less then I should and walked more. That's reflected in the pace. It's much better using the app, if only because it means I can put my phone away not carry it in my hand, but perhaps I need to dust off the old bluetooth headphones...
Also saw these awesome fungi during my warm-down walk.
