Well, I didn't really veer off the plan, I just changed the activity. Instead of a short run today, I went for an easy ski. The conditions right now are just too good to pass up. Picture perfect packed powder. There was a bit of wind, but as soon as I got in the woods it was barely noticeable. I decided to that in order to keep the heart rate down classic skiing would be the better choice. Since it was not much past 7:00, I had the trails to myself. All in all, a great morning.
Now, although I said and I'm convinced that the skiing is contributing to my hamstring tightness, I figured that if I took it really easy it wouldn't hurt. So, I skied really easy for about 50 minutes. And, after the ski, I stretched fairly well. Hopefully, no harm done. Either way, I felt much better for the rest of today. I didn't feel like I was dragging just walking around, so I think the rest has been good.
