AM - 9 miles with Ethan. On friday I was doing 800's on the grass, and hitting the times I wanted, but I was having a pain on the outside of my shin so I stopped. Afterwards it felt much worse, so I took a couple days off. First four mile we went pretty easy, then Ethan asked if we could speed up and I begrudgingly did. He kept putting in little surges, so on mile 9 I sped up a little bit. Nothing crazy, like 6:20 pace, so Ethan was like "Slow down dude" and I was just like what?? Anyway stretched after. Shin didn't hurt during the run but hurts now. Any advice would be great.
