For the first time in a while I had to deal with some real discomfort on the early stages of the run. The right hammy and in particular the semi-tendinous insertion were very sore after the first half mile or so. I didn't feel like I was running freely and was having to compensate. Debated cutting it short but around 2 miles in, stopped to fully stretch out the hammy, the calf and the quad before deciding whether or not to continue. Thankfully, the stretch did the trick and was able to continue on. After that it was a totally uneventful run & gym session.
