Slow yet painful

Came back a bit late. But started running after 7:30pm. I wore the SCSM 07 vest since it was a bit cold and my nose a little 'wet'.

I did my 7km in 55:20. Almost 8min/km average pace. Right ankle hurt and had to push on. My left knee also was painful during the slow run. It was just grit and run on. Wasn't gonna stop after a kilometer into it. I also noticed that I ran quite a bit underpronating earlier part of my run w/o realising it. Strange. Certified flat feet and yet underpronating. Since I'm wearing the NB 1223 stability instead of the Brookes 'The Beast' control shoes, I hope it's okay.
