Perfect weather! 38F, overcast, dry pavement, no wind. Man, I would take that every single day if I could.
My right hamstring that had been a little tight is finally pretty much back to normal. I have altered my cool/cold weather clothing approach a little to emphasize keeping my legs warmer (and torso a little cooler), to hopefully avoid tightness issues. Today I wore merino wool leggings under my track pants, while on top I wore just a poly long-sleeve tee under a thin windbreaker. My theory is to keep the legs warmer than the torso to fend off the tightness problem I was having. It seems to be working, or at least not hurting at all.
