Today's Plan: Run
I am finding it harder to get out in the morning. The early gray sky is just not inviting. But the air is invigorating enough that when I get home from work I am happy to head out. Wasn't sure how far I was going to get today. Another side effect I am having this week is a permanent stitch in my right side above my ribs. It's not debilitating, it's just dang annoying. Today it showed up before I hit a half mile and lasted until I got home.
I read an interesting post on a blog the other day about the differences between men and women and how running effects them differently. Unfortunately, men have women a bit beat on things like a larger heart and more red blood cells, which translates to more oxygen carried to muscles more quickly. Testosterone also stimulates muscle growth, while estrogen stimulates fat retention. While this seems bad on the face of it, women may be able to run further longer as we have more of an energy supply.
But personally I think the most obvious difference it that one week a month I, and I assume others, just can't perform as well. Men don't have that issue. A study by Oxford University predicted that as participation by female runners increases, the gap in times by men and women could decrease, especially in long distances. I think that is very likely. There are so many wonderful female runners out there.
