I don't have time to deal with the @exhaust error messages today sorry so I'm going manual.
I ran (and walked) 6.05km in 41m30s - six minutes running, one minute walking, six times. It felt comfortable, I didn't push myself and took the easy route that I know well. My ankle is improving. I've had only the odd twinge today since running.
The weather was absolutely perfect. Blue sky and sunshine at 8.30 this morning and about 15C - enough to feel the cool in the shade but not too chilly.
