Notes
My back spasmed as I was getting changed, so I waited for that to go away before I started. I was worried it would come back during the run, but it didn't bother me at all. It's happened a few times this week, I'm not sure why, and luckily the pain goes away pretty quickly.
Felt really good for the first 12k, the last 4 were hard, my pace was dead on until then.
My left knee was bugging me this morning for some reason, it didn't bother me during the run, but got sore afterwards.
